We have been given a table of quiz scores whose standard deviation is 5.6. We are asked to find the test scores that are within one standard deviation of the mean.
First of all, we will find the mean of the test scores using average formula.
The scores within one standard deviation would be mean plus one SD and mean minus one SD that is:
Therefore, the quiz scores 17.15 and 28.35 are within one standard deviation of the mean.
The correct answer is E. A fundamental basis of regression analysis is the assumption of the existence of two independent variables for every dependent variable.
Regression analysis is a statistical method that examines the dependence of a response variable on selected explanatory variables.
When studying the dependence between quantities and trying to describe a given functional dependence on a given formula, it is assumed that the dependence consists of a precisely determinable component and a random component. The relationship with this assumption is called the regression model.

Using the binomial distribution, it is found that the probability that he will hit fewer than 8 of the bottles is of 0.012, given by option A.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, we have that:
- The probability of a bottle being hit is of p = 0.95.
- There are n = 10 bottles.
The probability that he hits fewer than 8 of the bottles is given by:
In which:
Then:
Hence:
The probability that he will hit fewer than 8 of the bottles is of 0.012, given by option A.
