There is 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 YesO No A random sample of 164 recent donations at a certain blood bank reveals that 89 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 of0.01.

In a sample of 150 hospital emergency admissions with a certain diagnosis, 128 listed vomiting as a presenting symptom. Do these data provide sufficient evidence to indicate, at the 0.01 level ofsignificance, that the population proportion is less than 0.92? What is the null hypothesis? What is the test statistic? What is the p-value? What is the conclusion?
Recently, a large academic medical center determined that 7 of 15 employees in a particular position were male,whereas 56% of the employees for this position in the general workforce were male. At the 0.01 level of significance, is there evidence that the proportion of males in this position at this medical center is different from what would be expected in the general workforce? What are the correct hypotheses to test to determine if the proportion is different? A. H0:π≥0.56; H1:π<0.56 B. H0:π=0.56; H1:π≠0.56 C.H0:π≤0.56; H1:π>0.56 D.H0:π≠0.56; H1:π=0.56 Part 2 Calculate the test statistic. ZSTAT=enter your response here (Type an integer or a decimal.

A well-known brokerage firm executive claimed that at least 90% of investors are currently confident of meeting their investment goals. An XYZ Investor Optimism Survey, conducted over a two week period, found that in a sample of 800 people, 88% of them said they are confident of meeting their goals. What would be our formal conclusion about the null hypothesis at a 0.05 significance level?
It has been determined that 37 out of 100 adult Americans that did not attend college believe in extra-terrestrials. However, from a random sample of 100 adult Americans that did not attend college 43 claim that they believe in extra-terrestrials. Does this indicate that the proportion of people who did not attend college and who believe in extra-terrestrials has changed? Conduct a hypothesis test with a = 0.01 and interpret the results.
In a preliminary study, the U.S. Veterans Affairs Department found that 20.9% of the 81 soldiers who were near an accidental nerve gas release just after the 1991 Persian Gulf War had muscle and bone ailments, compared to a rate of 15.5% for the 52,000 Gulf veterans who were not near that area. Use an appropriate test and the 0.10 level of signi?cance in examining if there is significance difference between these two rates. Select one: a. The Null hypothesis that two rates are not different is rejected as p-value=0.07 is less than 0.10 b. The Difference between two rates is not significant as p-value=0.17 and is more than alpha=0.10 c. The Alternative hypothesis that two proportions are not equal is accepted as p-value=0.09 and is less than 0.1 d. The Alternative hypothesis that two proportions are equal is rejected as p-value=0.14 and is more than alpha=0.1
