144 recent donations at a certain blood bank reveals that a blood. Does this suggest that the actual percentage of type A donations differs from 40%, percentage of the population having type A blood? Carry out a test of the appropriate hypotheses using significance level of 0.01. A USE SALT State the appropriate null and alternative hypotheses.

Question
A random sample of 144 recent donations at a certain blood bank reveals that 86 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 0.01. In USE SALT State the appropriate null and alternative hypotheses. O H: p = 0.40 H:p < 0.40 O Ho: p = 0.40 H3ip > 0.40 O Ho: p + 0.40 H: p = 0.40 O H: p = 0.40 H:p + 0.40 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) Z = P-value = State the conclusion in the problem context. O Reject the null hypothesis. There is sufficient evidence to conclude that the percentage of type A donations differs from 40%. O Do not reject the null hypothesis. There is sufficient evidence to conclude that the percentage of type A donations differs from 40%. O Do not reject the null hypothesis. There is not sufficient evidence to conclude that the percentage of type A donations differs from 40%. O Reject the null hypothesis. There is not sufficient evidence to conclude that the percentage of type A donations differs from 40%. Would your conclusion have been different if a significance level of 0.05 had been used? O Yes O No
