Suppose we want to assess the effect of a one-day SAT prep class at a 5% level of significance. Scores on the SAT writing exam c

aalyn [17]

The conclusion is that since the value of 0.028 is less than 0.05 so we reject the null hypothesis at 5% level of significance and conclude that the mean of the difference in SAT writing scores for all students who take SAT prep class is equal to 0.

<h3>What is a null hypothesis?</h3>

A null hypothesis is a hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling error.

Here, the effect of a one-day SAT prep class at a 5% level of significance was assessed. Since the value of 0.028 is less than 0.05 so we reject the null hypothesis at 5% level of significance and conclude that the mean of the difference in SAT writing scores for all students who take SAT prep class is equal to 0.

Amanda and Fred are sister and brother. Amanda has twice as many sisters as brothers, and Fred has five times as many sisters as

pav-90 [236]

Answer:

In this family there are 5 girls and 2 boys

Step-by-step explanation:

Fred has five times as many sisters as brothers, so at least he has five sisters.

1. Let's suppose Fred has just one brother, in this case he would have five sisters (including Amanda). The condition that Fred has five times as many sisters as brothers is fufilled.

2. If Fred has one brother, it means that Amanda has two brothers

3. If Fred has five sisters (including Amanda), it means that Amanda has four sisters.

4. If Amanda has two brothers and four sisters, the condition that she has twice as many sisters as brothers is fufilled.

5. Then, in both cases, there are 5 girls and 2 boys:

Fred + 1 brother + 5 sisters = 2 boys, 5 girls

Amanda + 2 brothers + 4 sisters = 2 boys, 5 girls
