- A recent study on the effects of Tamiflu looked into whether the antiviral medication can reduce the duration of the flu or not. To test this, researchers selected sample of 42 individuals recently diagnosed with the flu. Twenty-one of these individuals were given a placebo, and their average flu durations was 12.6 days (SD = 1.88). The remaining 21 subjects were given Tamiflu, and their average flu duration was 11.4 days (SD = 1.58). Did Tamiflu make reduce the duration of the flu? What is the effect size for this difference? state the null and alternavive hypthesis, aplha level of 0.05 please text the null hypthesis and draw the rejction regionAs part of a study to determine the effects of a certain oral contraceptive on weight gain, 12 healthy females were weighed at the beginning of a course of oral contraceptive usage. They were reweighed after 3 months. Do the results suggest evidence of weight gain? Use α = .05.A research study examined the effects of a new drug versus an old drug on hypertension. There were 172 people enrolled in the new drug group, and 125 of them were hypertensive. For the old drug group, 165 people were enrolled and of those, 76 were hypertensive. Was there a difference in the proportion of people who were hypertensive between the new drug and the old drug? Calculate the z or t test statistic
- The sensitivity of a screening test is .95, and its specificity is .85. The rate of the disease for which the test is used is .002. What is the predictive value positive of the test?The drug Tamiflu (oseltamivir phosphate) is used to attack the influenza virus to reduce symptoms for patients. The manufacturer label states that 6% of patients will develop nausea as a side effect. Patients report that nausea occurs at a higher rate than the label indicates. In clinical trials, among 724 patients treated with Tamiflu, 72 experienced nausea as a side effect. Using an α=0.05 level of significance, complete the following steps to determine whether the rate of developing nausea is higher than the manufacturer’s label. (NOTE: All areas are reported to four decimal places; all z-scores are reported to two decimal places except the two special cases listed at the bottom of the table.)

A warden suspects that this percent is higher if the sex offender is also a drug addict. Of the 318 convicted sex offenders who were also drug addicts, 54 of them became repeat offenders. What can be concluded at the αα = 0.05 level of significance?
