Systolic Blood Pressure for Women: Systolic blood pressure results from contraction of the heart. Based on past results from the National Health Survey, it is claimed that women have systolic blood pressures with a mean and standard deviation of 130.7 and 23.4, respectively. Use the systolic blood pressures of women listed in the below Data Set to test the claim that the sample comes from a population with a standard deviation of 23.4.

A sample mean, sample size, and population standard deviation are given. Use the P-value approach to perform a one-mean z-test about the mean of the population from which the sample was drawn.
x bar= 78, n = 28, sigma = 11, Hnought: mu=72, Hone: mu>72 , alpha = 0.01
First find the proper z value then use this to find the

Why is it important to know the standarddeviation for a given sample? What do researchers learn about a normal distribution from knowledge of the standarddeviation? A sample of n=20 has a mean of M = 40. If the standarddeviation is s=5, would a score of X= 55 be considered an extreme value? Why or why not?
Can you please d

A sample of 40 observations is selected from one somewhat normal population. The sample mean is 102 and the sample standarddeviation is 5. A sample of 50 observations is selected from a second source. The sample mean was 99 and the standarddeviation was 6. Conduct a test of the hypothesis using the .04 level of significance.

A lumber company has claimed that the standarddeviation for the lengths of their 6 foot boards is 0.5 inches or less. To test their claim , a random sample of 17 six-foot boards is selected; and it is determined that the standarddeviation of the sample is 0.42. Do the results of the sample support the company's claim? Use alph

You want to prove that a population mean is not 7. Data is ratio and a large sample size will be used (n = 225). When the sample is done the sample mean is computed to be 7.2 and the sample standarddeviation is 1.5. Test the hypothesis using an alpha of 5%. Use formal hypothesistesting and compute the p-value.

Your manager has speculated the following:
a. the average (mean) annual income was less than $50,000,
b. the true population proportion of customers who live in an urban area exceeds
40%,
c. the average (mean) number of years lived in the current home is less than 13
years,
d. the average (mean) credit balance

I need the analysis in Minitab and the same analysis in MS WORD, I do not have minitab on my comp here that is why I am having a problem. So give everything in word too. I will see the minitab file once i go to school.
