Answer:
1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
Step-by-step explanation:
A p - value less than 0.05 means that the test hypothesis is false or rejected.
In this question the test hypothesis is H 0 : mu=79 which is false as p-value is 0.035.
Whenever the p- value is less than the significance level H0 is rejected.
Hence the null hypothesis is rejected.
Therefore only choice 1 is correct.

Simple interest is $ 9
<em><u>Solution:</u></em>
Given that,
P = $ 400
T = 0.25 years
<em><u>The formula for simple interest is:</u></em>
Where,
I is the simple interest earned
R is the rate of interest in decimal
T is the number of years
<em><u>Substituting the values we get,</u></em>
Thus simple interest is $ 9
A correct possibility could be $37.50 because 37.50 x 2 + 4 = 79
