What percentage of the 50 regions have stores within 1, 2, or 3 standard deviations of the mean?
Approximately 99.7% of the data fall within three standard deviations of the mean.
In particular, the empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)
The empirical rule, also referred to as the three-sigma rule or 68-95-99.7 rule, is a statistical rule which states that for a normal distribution, almost all observed data will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).
In particular, the empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).

Which probability value indicates that there is statistical significance? 0.0345 0.4595 0.9534 0.9967
The probability value indicates that there is statistical significance in 0.0345 option (a) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
As we know,
Statistical significance is commonly defined as a probability value of 0.05 or even less. P-value can be used in replacement of or in addition to preset levels of confidence when testing the claim.
The value 0.0345 < 0.05
The probability value of 0.0345 indicates that there is statistical significance
Thus, the probability value indicates that there is statistical significance in 0.0345 option (a) is correct.

The marching band is holding a fundraiser. The band is selling t-shirts for $20 and yearbooks for $24. The goal is to sell at least $2,400 in merchandise. Which of the following is a solution to this scenario?
50 t-shirts and 59 yearbooks
51 t-shirts and 57 yearbooks
60 t-shirts and 48 yearbooks
62 t-shirts and 48 yearbooks
The answer to this question is 50 t-shirts and 59 yearbooks
We get that the solution to this scenario will be 50 t-shirts and 59 yearbooks.
Selling price of t shirts = $ 20
Selling price of year books = $ 24.
Let the number of t shirts sold be x and the number of yearbooks sold be y.
Goal to sell at least = $ 2400 in merchandise.
So, we get the equation as:
20 x + 24 y ≥ 2400
5 x + 6 y ≥ 600
Now, we are given some options:
50 t-shirts and 59 yearbooks
Substituting it, we get that:
5 ( 50) + 6 ( 59) ≥ 600
250 + 354 ≥ 600
604 ≥ 600
which is true.
51 t-shirts and 57 yearbooks
Substituting it, we get that:
5 ( 51) + 6 ( 57) ≥ 600
255 + 342 ≥ 600
597 ≥ 600
which is not true
60 t-shirts and 48 yearbooks
Substituting it, we get that:
5 ( 60) + 6 ( 48) ≥ 600
300 + 288 ≥ 600
588 ≥ 600
which is not true
62 t-shirts and 48 yearbooks
Substituting it, we get that:
5 ( 62) + 6 ( 48) ≥ 600
310 + 288 ≥ 600
598 ≥ 600
which is not true.
Therefore, we get that the solution to this scenario will be 50 t-shirts and 59 yearbooks.

Matt and Ryan are playing an exciting round of Rock Paper Scissors: The Collectible Card Game. Matt is convinced that Rock can beat anything, so his deck consists only of 8 Rock cards. Ryan's deck consists of 5 Paper cards and 3 Scissors cards. In the game, Matt randomly selects 3 cards from his deck and places them on the table. Ryan then randomly selects 3 cards and places one on each of Matt's cards. If Rock beats Scissors, Scissors beats Paper, and Paper beats Rock, then what's the probability that Ryan beats Matt in a landslide by choosing 3 Paper cards in a row?
Using the hypergeometric distribution, there is a 0.1786 = 17.86% probability that Ryan beats Matt in a landslide by choosing 3 Paper cards in a row.
What is the hypergeometric distribution formula?The formula is:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.N is the size of the population.n is the size of the sample.k is the total number of desired outcomes.For this problem, we have that Ryan will win if he takes 3 Paper cards from a set of 8(5 paper and 3 scissors), hence the parameters are given as follows:
N = 8, k = 5, n = 3, x = 3.
Hence the probability is given by:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 3) = h(3,8,3,5) = \frac{C_{5,3}C_{3,0}}{C_{8,3}} = 0.1786[/tex]
0.1786 = 17.86% probability that Ryan beats Matt in a landslide by choosing 3 Paper cards in a row.

If a population has 500 individuals in it in 2010, and the per capita birth rate is 0.3 and the per capita death rate is 0.2, is the population growing or shrinking?
The population is growing as the births are more than deaths in an year.
What is Population Growth?Increases in a population's or a dispersed group's membership are referred to as population growth.
Given:
Total population = 500Per capita birth rate = 0.3Per capita death rate = 0.2To find: Is population growing or shrinking?
Finding:
Number of new-borns in an year = total population (per capita birth rate) = 500(0.3) = 150Number of deaths in an year = total population (per capita death rate) = 500(0.2) = 100Difference in the number of births and deaths = 150 - 100 = 50Hence the population is growing as the births are more than deaths in an year.

The volume of the cone is 96 cm^3 and the radius is 6 cm. What is the height of the cone?
If the volume of the cone is 96 cm^3 and the radius is 6 cm then the height of the cone is equal to 2.55 cm.
The height of the cone can be defined as the extent of the altitude of the cone. The height of a cone can be determined using its volume and radius values. The formula for the volume of a cone can be given as:
V= πr²h/3
Here, V is the volume of the cone, r is the radius of the cone and h is the height.
This equation can be rearranged to find the value of height as follows,
h=3V/πr²
Now, add the given values to the equation,
h= 3(96)/π(6²)
h= 288/π(36)
As π = 3.14
h= 288/3.14(36)
h= 288/ 113.04
h= 2.55 cm
