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.
Answer:

addition and subtraction
there are more fish in the school
the number of fishes that left the school is less than the number of fish that joined the school
Step-by-step explanation:
fishes that swam away = 375 - 47 = 328
fish that joined = 328 + 116 = 444
to determine the fish that swam away subtract. to determine the fish that joined, add.
116 is greater than 47. so there are more than 375 fish in the school

Hey buddy, here is your answer. Hope it helps you.
Step-by-step explanation:
As angle CAB is a linear pair and is 109 degrees. We need to simply subtract it by 180. So 180-109=71. So angle CAE is 71 degrees.
I believe your answer will be 10
