True or False? Assume a researcher recruits 150 African American and Caucasian individuals taking warfarin to determine if there is a difference in the mean dosage of the medication needed to cause a decrease in their INR blood test. If the mean dosage for 75 Caucasian individuals required to get their INR blood test in range is 6.1 mg with a standard deviation of 1.7 mg and the mean dosage for 75 African American individuals required to get their INR blood test in range is 4.3 mg with a standard deviation of 0.9 mg, the S p value obtained while calculating the test statistic is approximately 1.14 mg. True False

12. (Two Samples) According to a survey, the mean price of gasoline in the United States was $1.20 per gallon in 1995 and $1.10 per gallon in 1994. (U.S. News & World Report, June 12, 1995). Suppose these means were based on random samples of 100 gasoline stations for 1995 and 120 gasoline stations for 1994. Also, assume that the sample standard deviations were $0.11 for 1995 and $0.10 for 1994. a. Construct a 98% confidence interval for the difference between the mean gasoline prices for 1995 & 1994. b. Test at the 1% significance level if the mean gasoline price was higher in 1995 than in 1994.

6-4 #17 PLEASE ANSWER ALL QUESTIONS. THANK YOU Transgender Surgery Exercise 6.106 introduces a study investigating the age at which transgender people begin to transition gender and the age at which they have their first experience of gender dysphoria. The study also recorded the age at which they began gender-affirming surgery, and we examine here whether there is a difference in mean age of surgery between trans men and trans women. In the study, the mean age for the 155 trans women in the sample was 41.3 years with a standard deviation of 16.3. The mean age for the 55 trans men in the sample was 35.4 with a standard deviation of 10.8. . Does this sample provide evidence that the mean age of surgery is different between trans women and trans men? (Let Group 1 represent trans women and Group 2 represent trans men.) Find test statistic and p-value. Test statistic = (round to three decimal places)p-value = (round to three decimal places)…
question(10a): What type of statistical test that could used to test the following hypothesis. (A) there are 92 public colleges and universites in Canada. The average tution in 2016-2017 was $6392 per year(2 semesters) You believe that the tution has increase signifcantly for 2016-2017 school year. You sample the published tution fee for 12 schools across Canada . You find the mean tution fee for the same period is $6879 with a standard deviation of $568. (ii) Researchers were interested in the effects of lead consumption through contaminated water in Flint, MI on the intelligence of children. They sample 25 children at the local elementary school and gave them the WISC test. In a typically developing population in the US, the WISC has a mean score of 100 and astandard deviation of 15. The researchers believe that the lead consumption that had been on going since 2014.When they average the WISC for the 25 children in Flint they the mean IQ of 93.5
