Answer: Many of you know this, but why is this a thing? You don't go to Subway and pay for a $5-footlong expecting to get 11 inches (although many of you will argue this is the case). And it's not just a 2x4: A 1x4 is actually ¾ inches by 3-½ inches; a 4x4 is actually 3-½ inches by 3-½ inches.
Step-by-step explanation:
A) z value = (x - π) / <span>σ = 100 - 133 / 23 = -1.43
p(<= 100) = 0.0764

A is the answer domain is the x
Answer:
Slope of the line segment PQ is 1/2.
Step-by-step explanation:
We are given with a line connecting two points P and Q.
The coordinates of P are (4,4) and the coordinates of Q are (-2,1).
Slope of line joining two points
and 
is given by the formula 
Hence the slope of the line PQ is 
Therefore correct option is 'C' that is 1/2.
Answer: (B)
Step-by-step explanation:
An independent sample test compares two sample means in order to determine the statistical significance of the difference between their population means.
The independent sample test would be the best hypothesis test for this study because:
1. There was a random samples of data from the population
2. There was no relationship between the subjects in each sample. That is;
- subjects in the first group were not also in the second group
- subjects in the first group did not influence subjects in the second group and vice versa.
3. There was independence of observations in this study. Each subject in each group was separately observed and each subject has a given fitness performance score.
4. There are values on both the dependent and independent variables.
- the dependent variable is FITNESS PERFORMANCE and for each subject, it is dependent on either the OLD EXERCISE PROGRAM or the NEW EXERCISE PROGRAM.
5. Our dependent variable her is a continuous variable as we see from the range of fitness scores. The lowest score is 19 and the highest score is 73. This shows that the variable is continuous. All the other scores fall in between.
6. Our independent variable is a categorical variable. Categorized into OLD EXERCISE PROGRAM and NEW EXERCISE PROGRAM.
