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.

Since the ratio is 1 to 1.5, the measurement 30 inches must correspond to 1. Thus multiply 1.5 by 30.
30*1.5 = 45
Your answer should be 45. An alternate way could be to go through all of them but for me I personally prefer this way as it is much faster and easier. Hope this helps!
