Do not use R, solve this entire question 2) In women, calcitonin levels decrease after menopause. A study to examine this was done in 1989 byReginster et. al. They found the following results in pg/ml (you may use R if you wish):Before menopause:86104 7486 86 50 837111983After menopause:42255172Use a Mann-Whitney U test. Use a = .01. Do calcitonin levels drop after menopause?

A diet center wanted to test three different methods for losing weight to determine if the average weight loss (reported in pounds/week) for each method is the same. The results for the three methods are tabulated below. Given that there is a significant difference between the three methods, use the Tukey test to determine if there is a significant difference between each pair of methods. Let a=0.05.

Sulfur compounds cause "off‑odors" in wine, so winemakers want to know the odor threshold, the lowest concentration of a compound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 25 micrograms per liter of wine (?g/L ). The untrained noses of consumers may be less sensitive, however. The DMS odor thresholds for 10 untrained students are given. 30 30 42 35 22 33 31 29 19 23 (a) Assume that the standard deviation of the odor threshold for untrained noses is known to be ?=7?g/Lσ To access the complete data set, click the link for your preferred software format: Do the three simple conditions hold in this case? Make a stemplot and use it to check the shape of the distribution. (b) STATE: What is the average (mean) DMS odor threshold, ?μ , for all untrained people? PLAN: Using the four‑step process, give a 95%95% confidence interval for the mean DMS odor threshold among all students. SOLVE: We have assumed that we…
Fifteen different video games showing alcohol use were observed. The duration times of alcohol use (in seconds) were recorded. When using this sample for a t test of the claim that the population mean is greater than 92 sec, what does df denote, and what is its value? What does df denote? What is the value DF is
a study was done involving data from all major US cities that compares the number of parks in each city to the average number of times an individual exercises each week. Pearson's r=.76 What does the value of r suggest?
Thirty different video games showing drug use were observed. The duration times of drug use (in seconds) were recorded. When using this sample for a t test of the claim that the population mean is greater than 92 sec, what does df denote, and what is its value? what's the value of df?
A large automobile insurance company selected samples of single and married male policyholders and recorded the number who made an insurance claim over the preceding three-year period. Single Policyholders Married Policyholders ni = 412 n2 = 778 Number making claims = 75 Number making claims = 111 a. Use a= 0.05. Test to determine whether the claim rates differ between single and married male policyholders. z-value (to 2 decimals) p-value (to 4 decimals) We cannot conclude that there is the difference between claim rates. b. Provide a 95% confidence interval (to 4 decimals) for the difference between the proportions for the two populations. Enter negative answer as negative number.
