Im so sorry for spamming

Question 1: Test the hypothesis using the​ P-value approach. Be sure to verify the requirements of the test. Upper H 0 : p equals 0.84 versus Upper H 1 : p not equals 0.84, n equals 500, x equals 410 comma alpha equals 0.05 Is np 0 left parenthesis 1 minus p 0 right parenthesis greater than or equals 10np01−p0≥10​? Select the correct choice below and fill in the answer box to complete your choice. ​(Type an integer or a decimal. Do not​ round.) A. ​Yes, because np 0 left parenthesis 1 minus p 0 right parenthesisnp01−p0equals= nothing. B.​No, because np 0 left parenthesis 1 minus p 0 right parenthesisnp01−p0equals= nothing. Now find ModifyingAbove p with caretp. ModifyingAbove p with caretpequals= nothing ​(Type an integer or a decimal. Do not​ round.) Find the test statistic z 0z0. z 0z0equals= nothing ​(Round to two decimal places as​needed.) Find the​ P-value. ​P-valueequals= nothing ​(Round to three decimal places as​ needed.) State the conclusion of the hypothesis test. ▼ Reject the null hypothesis, Do not reject the null hypothesis, because the​ P-value is ▼ less greater than alphaα.

Question 2: In a clinical​ trial, 17 out of 833 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 1.5​% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 1.5​% of this​ drug's users experience flulike symptoms as a side effect at the alpha equals 0.05 level of​ significance?

Question 3: Twenty years​ ago, 49​% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 242 of 800 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years​ ago? Use the alpha equals 0.05 level of significance.

What are the null and alternative​ hypotheses?

ho: versus H1:

B: verify that the normal model may not be used to estimate the P-Value

because np0(1-p0)=3.7<10, the normal model may or may not be used to approximate the p-value.

c: explain why this is a binomial experience

D: determine the P-Value
