(a) A new drug is being compared with a standard drug for treating a particular illness. In a clinical trial, a group of two hundred patients was split into two equal groups receiving either the new drug or the standard drug. The condition improved in 85% of patients who received the new drug and in 72% of patients who received the old drug. Carry out an appropriate hypothesis test at the 5% significance level to investigate whether the new drug is better than the standard drug. Construct a 95% confidence interval for the difference in the two proportions.

Question

(a) A new drug is being compared with a standard drug for treating a particular
illness. In a clinical trial, a group of two hundred patients was split into two
equal groups receiving either the new drug or the standard drug. The
condition improved in 85% of patients who received the new drug and in 72%
of patients who received the old drug. Carry out an appropriate hypothesis test
at the 5% significance level to investigate whether the new drug is better than
the standard drug.
Construct a 95% confidence interval for the difference in the two proportions.

Please help me better understand how to properly solve. A randomized controlled experiment in Charlotte, North Carolina, studied three police responses to spousal abuse: advise and possibly separate the couple, issue a citation to the offender, and arrest the offender. The effectiveness of the three responses was determined by re-arrest rates. The photo shows the rates. Research wishes to test null hypothesis that that the proportions of subsequent arrests are the same regardless of the treatment assigned. Under the null hypothesis, determine the expected number of times no subsequent arrest would occur for the treatment “Advise/separate”?
A new shampoo is being test-marketed. A large number of 16 ounce bottles were mailed out at random to potential customers in the hope that the customers will retuen an enclosed questionnaire. Out of tbe 1500 returned questionnaires, 975 indicated that they like the shampoo and will consider buying ir when it becomes available on the market. Perform a hypothesis to determine if the proportion of potential customers is at most 65 percent. Use a level of significance of 0.05.
According to the most recent General Social Survey, 70% of adults watch TV nightly. A researcher believes that the proportion of college students who watch TV nightly is less than this. To test this claim the research samples 400 college students and finds that 276 watch TV nightly. At the 0.05 level of significance does this data provide evidence to suggest that the proportion of college students who watch TV nightly is less than 70%?

In a clinical trial of a drug intended to help people stop smoking, 125 subjects were treated with the drug for 12 weeks, and 14 subjects experienced abdominal pain. If someone claims that more than 8% of the drug's users experience abdominal pain, that claim is supported with a hypothesis test conducted with a 0.05 significance level. Using 0.17 as an alternative value of p, the power of the test is 0.95. Interpret this value of the power of the test. The power of 0.95 shows that there is a % chance of rejecting the hypothesis of p = when the true proportion is actually That is, if the proportion of users who experience abdominal pain is actually then there is a % chance of supporting the claim that the proportion of than 0.08. users who experience abdominal pain is (Type integers or decimals.

A manufacturer of laptop computers claims that only 1% of their computers are defective. In a sample of 600 computers, it was found that 3% were defective. If the proportion of defectives were really only 1%, there would be than 1 chance in 1000 of getting such a large proportion of defective laptops in the sample. Is there statistically significant evidence against the manufacturer's claim? Why or Why not?

An advertising agency collected a random sample of 300 businesses targeted with an advertising campaign for a large commercial bank. The sample was used to investigate the efficacy of the advertising campaign. One of the variables measured was whether the business was considering becoming a client of the bank. Of the businesses sampled, 50 of the 300 businesses reported that they were considering becoming a client of the bank. A hypothesis test was conducted to determine if this provides evidence that less than 20% of all businesses were considering becoming a client of the bank. Calculate the test statistic to two decimal places (2dp). Test statistic =
