Problem 8.37

A random sample of 150 recent donations at a certain blood bank reveals that 82 were type A blood. Does this suggest that the actual percentage of type A donations differs from 40%, the percentage of the population having type A blood? Carry out a test of the appropriate hypotheses using a significance level of .01. Would your conclusion have been different if a significance level of .05 had been used?

Step-by-Step Solution:
Step 1 of 3

Stats 401 Week 2 Relative frequency = How many times appeared in category ÷ Total items in category (like finding percent without multiplying by 100 at the end) For the median, if there is an even amount of number given then add the two middle terms then divide by 2. EX: 1 2 3 4 5 6. The two middle terms are 3 and 4 so 3 + 4 = 7. Then 7/2 = 3.5 (finding the average of those numbers). If there isn’t a mode (1 2 3 4 5 6) then write “NO MODE” not “The mode is zero” because that implies that there is the number 0 and that is what appears the most. Peak of curve is in the middle When the mean = median = mode the distribution is bell shaped or symmetric. Median > mean then it is left skewed Med
