In a recent court case it was found that during a period of 11 years 864 people were selected for grand jury and 40% of them were from the same ethnicity. Among the people eligible for grand jury duty, 80.9% were of this ethnicity. Use a 0.05 significance level to test the claim that the selection process is biased against this ethnicity to sit on the grand jury. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and the final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution. (a) Identify the null and alternative hypothesis. (Type integers or decimals. Do not round. Spell the words of the symbols, ex: p-hat, x-bar, mu, etc, and use =/ for if necessary.) H0: H1: (b) Identify the test statistic. (Round to two decimal places as needed.) (c) Identify the P-value. (Round to three decimal places as needed.) (d) State the conclusion about the null hypothesis, as well as final conclusion that addresses the original claim. the null hypothesis because the P-value is than the significance level . There sufficient evidence at the 0.05 significance level to the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury.

Listed below are the lead concentrations (in g/g) measured in different Ayurveda medicines. Ayurveda is a traditional medical system commonly used in India. The lead concentrations listed here are from medicines manufactured in the United States. Assume that a simple random sample has been selected. Use a 0.05 significance level to test the claim that the mean lead concentration for all such medicines is less than 14.0 g/g. 2.97 6.54 6.02 5.51 20.46 7.45 12.03 20.48 11.50 17.53 (a) Identify the null and alternative hypothesis.

The Ericssоn methоd is оne of severаl methods clаimed to increаse the likelihood of a baby girl. In a clinical trial, results could be analyzed with a formal hypothesis test with the alternative hypothesis of p > 0.5, which corresponds to the claim that the method increases the likelihood of having a girl, so that the proportion of girls is greater than 0.5. If you have an interest in establishing the success of the method, which of the following P-values would you prefer? The P-value of is preferred because it corresponds to the sample evidence that most strongly supports the hypothesis that the method effective.
