Answer
(B)The probability is very small (<.03) that he would find a difference between these two groups that was this large (in his sample), if in fact listening to nostalgic music had no influence on life satisfaction (in the population).
Step-By-Step Explanation:
The p-value is defined as the odds of obtaining the data you collected, assuming we have proved the null hypothesis to be true. In the study above, the null hypothesis is that “Listening to nostalgic music has no impact on life satisfaction”.
The most accurate summary of what the p-value means is that there is a very small (<.03) probability that Professor Bonus would find a difference between the two groups (those who listened to nostalgic pop music and those who did not). in his study. From his sample of study, listening to nostalgic music had no influence on higher life satisfaction in the population.
$41.04 you multiply how long and how wide it is together. after that that the answer is 2,070 then divide it by 50 and you get $41.04.

B) c - 1/5c - 40 = 120
c- (original cost) - 1/5c (sale) - 40(coupon)= 120(final cost)
Hope that helps! :)
Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon
Here n is the number of sides of polygon
In the given polygon
n = 7
So,
Hence,
The sum of interior angles of given polygon is 900°
