Description: Use a 0.05 significance level to test the claim that males and females have the same mean BMIMale BMIn=80* = 26.3s = 5.4Female BMIn=61I = 28.4s = 7.4

The claim is males and females both have the same BMI. The given data is, n1=80, x1=26.3, S1=5.4n2=61, x2=28.4, S2=7.4 The hypothesis is, H0:The BMi of males and female is same.H1: The BMI of males and females is not same. The test statistic is, t=x1-x2Sp2*(1n1+1n2)Where, Sp2=S21*(n1-1)+S22*(n2-1)n1+n2-2t=26.3-28.66.34*(180+161)=-2.1338The p-value = 2* P(T< Test statistic) =0.0346 ....Using software. Decision:- As p-value =0.0346 < level of significance α=0.05 therefore, reject the null hypothesis at 5% of the level of significance. Conclusion:- There is a difference between the BMI of males and females.

The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with o = 600 miles. Suppose that a random sample of 31 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.8 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from (higher or lower than) the national average? Use a 0.05 level of significance.

Use the 1odwing Wildlife: Coyotes A random sample of 46 adult coyotes in a region of northern Minnesota showed the average age to be z = 2.05 years, with sample standard deviation 8 = 0.82 years (based on information from the book Coyotes: Biology, Behavior and Management by M. Bekoff, Academic Press). However, it is thought that the overall population mean age of coyotes is µ=1.75.

Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women
In a company, the known mean time before the first occupational accident is normally distributed with a mean of 12 years and a variance of 6.76 years². What is the probability that an individual happens to have an accident between 11.3 and 13.6 years of permanence in the company?
A public bus company official claims that the mean waiting time for Bus # 14 during peak hours is approximately 10 minutes. Karen took Bus # 14 during peak hours on 36 different occasions. Her mean waiting time was 8.7 minutes. Assume that the population standard deviation o of 2.9 minutes is known. At the 0.01 significance level, test if the mean of all the peak hours waiting time for Bus # 14 is significantly different from 10 minutes.

A sample of 36 students is found to have a mean score on GMAT Math test was (A + 500). The standard deviation is A scores. The same supervisor in the last example like to see if a student 5. scored significantly below the population mean score on the GMAT Math test 515. Is there sufficient evidence to support the claim at 10% level of significance? Note that: A is first two-digit number (before English alphabet letter) from your college ID. B is last four-digit number (after English alphabet letter) from your college ID. For example, if your MEC ID is 16F23451, then A = 16 and B = 3451
