What is the test statistic?What is the P-value?What is the P-value method?Make a final conclusion. In a recent court case it was found that during a period of 11 years 871 people were selected for grand jury duty and 37% of them were from the same ethnicity.Among the people eligible for grand jury duty, 80.7% were of this ethnicity. Use a 0.01 significance level to test the claim that the selection process is biased againstallowing this ethnicity to sit on the grand jury. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and finalconclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.Which of the following is the hypothesis test to be conducted?O A. Ho: p= 0.807О В. Но: р30.807H1: p+0.807H: p> 0.807O D. Ho: p> 0.807H1: p= 0.807ОС. Но р< 0.807H1: p=0.807O E. Ho: p# 0.807F.

Hypnosis and Pain. In the paper “An Analysis of Factors That Contribute to the Efficacy of Hypnotic Analgesia” (Journal of Abnormal Psychology, Vol. 96, No. 1, pp. 46–51), D. Price and J. Barber examined the effects of hypnosis on pain. They measured response to pain using a visual analogue scale (VAS), in centimeters, where higher VAS indicates greater pain. VAS sensory ratings were made before and after hypnosis on each of 16 subjects. A hypothesis test is to be performed to decide whether, on average, hypnosis reduces pain. a. identify the variable. b. identify the two populations. c. identify the pairs. d. identify the paired-difference variable. e. determine the null and alternative hypotheses. f. classify the hypothesis test as two tailed, left tailed, or right tailed.

Twenty years ago, 52% 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 281 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 a=0.1 level of significance. *** Because npo (1-Po) = 199.7 less than 5% of the population size, and the sample can be reasonably assumed to be random, the 10, the sample size is requirements for testing the hypothesis are satisfied.
