The average salary of 36 state employees who do similar work is $58,970 with σ=$1500 At the 0.01 level of significance, can it be concluded that state employees earn on average less than federal employees... Is it a one or two-tailed test?
Suppose 214 subjects are treated with a drug that is used to treat pain and 52 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. i) Identify the statistic for this hypothesis ii) Determine the P-value iii) State the conclusion
A new treatment for a severe allergy is claimed to have a better cure rate than the standard of care, which has 60% of cure rate. A random sample of 50 patients, suffering from allergy, are given the new treatment and as a result 34 are cured.a) Is the claim valid for a significance level of 0.05? Use p-value analysis.b) If you conclude that the claim is not valid, i) what would be the required sample size to support the claim? ii) otherwise, what would be the required sample size to unsupport the claim For the analysis in part b assume that the percentage change in n and number of cured patients are exactly the same, i.e. if n is doubled, that is n = 100, than number of cured people will also be doubled, i.e. 68 etc.)
An experiment was conducted to test if 2 new anti-anxiety medications will have an effect on number of anxiety symptoms. The researcher randomly assigned participants to one of the three experimental groups. Groups 1 and 2 took the 2 new medications while Group 3 took a placebo pill. The researcher was interested in determining whether there would be a difference in the number of anxiety symptoms among the three groups. Assume an alpha level of 0.05 and a two-tailed test. What statistical test should you use to evaluate the hypothesis above? one-way independent ANOVA Pearson Product-Moment Correlation simple linear regression multiple linear regression three-way independent ANOVA

3. A study examined the effect of protein consumption on weight gain in rats. Investigators obtained 61 female rats and randomly assigned 30 of them to a lowprotein diet and the other 31 to a high-protein diet. After 60 days, the weight gained by each rat was recorded (in grams). Researchers want to know if the mean weight gain for the low-protein diet was different than the high protein diet. c. Based on the P-value, what conclusion can be drawn at a 5% significance level? p value = 0.07072
