If the group consumed an average of81 grams per day with a standard deviation of 10 grams per day, is it valid toconclude at 0.05 level of significance, that the female adolescent of this age groupfrom this City consume more than Vitamin C per day than the recommendedconsumption?Identify the appropriate hypotheses.HoiHS81(AHaitH>81Ho:μ=81(BHaid>81HoiHs75Hait>75Ho:μ=75HaiH>75O 46 minutes remaining

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
