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 appropriate hypotheses using a significance level of 0.01. Would your conclusion have been different if a significance level of 0.05 has been used?

Ответ:
Yes, type A donations differs from 40%.
No, conclusion remained same.

See attached pictures.
Ответ:
Start off with 100%. Now, subtract 3/5, or 60%, to get 40%.
Take 1/4, or 25%, of 40% away. This means you subtract another 10% from 40%, leaving 30%. There’s the answer.
