A study was conducted to determine if the performance of a certain type of surgery on young horses had any effect on certain kinds of blood cell types in the animal. Fluid samples were taken from each of six foals before and after surgery. The samples were analyzed for the number of postoperative white blood cell (WBC) leukocytes. A preoperative measure of WBC leukocytes was also measured, with the accompanying results. Use a paired sample t-test to determine if there is a significant change in WBC leukocytes with the surgery.

A study was conducted to determine if the performance of a certain type of surgery on young horses had any effect on
certain kinds of blood cell types in the animal. Fluid samples were taken from each of six foals before and after surgery.
The samples were analyzed for the number of postoperative white blood cell (WBC) leukocytes. A preoperative
measure of WVBC leukocytes was also measured, with the accompanying results. Use a paired sample t-test to
determine if there is a significant change in WBC leukocytes with the surgery.

Calcium is the most abundant mineral in the body and also one of the most important. The recommended daily allowance (RDA) of calcium for adults is 800 milligrams (mg). A random sample of 18 people with incomes below the poverty level gives the following daily calcium intakes: 686, 433, 743, 647, 734, 641, 993, 620, 574, 634, 850, 858, 992, 775, 1113, 672, 879, 609 At the 1% significance level, do the data provides sufficient evidence to conclude that the mean calcium intake of all people with income levels below the poverty level is less than the RDA of 800 mg?

As part of an overall evaluation of training methods, an experiment was conducted to determine the average exercise capacity of healthy male army inductees. To do this, each male in a random sample of 35 healthy army inductees exercised on a bicycle ergometer (a device for measuring work done by the muscles) under a fixed workload until he tired. Blood pressure, pulse rates, and other indicators were carefully monitored to ensure that no one’s health was in danger. The exercise capacities (mean time, in minutes) for the 35 inductees are listed in the data 1. The original question asks for a 95% confidence interval, but I know how to do that. my question is, how do you decide what distribution to use? We do not know the population standard deviation, so I would say t, but isn't one of the assumptions associated with t distribution that the sample be normally distributed? these data aren't normal (by Anderson darling test and qq plot) 2. What are the assumptions of a t distribution? of a…
An article included data from a survey of 2587 hiring managers and human resource professionals.The article noted that many employees are using social networks to screen job applicants and that this practice is becoming more common. Of the 2587 people who participated in the survey, 1300 indicated that they use social networking sites ( such as Facebook, MySpace, and LinkedIn) to research job applicants. For the purposes of this exercise, assume that the sample is representative of hiring managers and human resource professionals. d. suppose that researchers wanted to estimate the proportion of hiring managers and human resource professionals who screen job applicants using social networks. determine the sample size required to estimate the proportion of employers using social networks to screen job applicants to within .03 with 99% confidence. ( round your answer up to the nearest whole number ) hint: use formula that is used when the p estimate is unknown
Polyunsaturated fatty acids in the diet favorably affect several risk factors for cardiovascular disease. The principal dietary polyunsaturated fat is linoleic acid. Suppose we randomly selected twelve adults for our study. We took their blood pressure measurements (systolic blood pressure) at the start and recorded them for each adult. Then we placed required these adults to consume 23g/day of safflower oil which is high in linoleic acid for four weeks. At the end of the four weeks, we took another systolic blood pressure(SBP) measurement. The paired data is provided below: Subject 1 2 3 4 5 6 7 8 9 10 11 12 Baseline SBP 119.67 100.00 123.56 109.89 96.22 133.33 115.78 126.39 122.78 117.44 111.33 92.39 1-month SBP 117.33 98.78 123.83 107.67 95.67 128.89 113.22 121.56 126.33 110.39 107.00 93.06 Use the appropriate nonparametric test at alpha level of 0.05, to test whether the diet heavy in linoleic acid increases systolic blood pressure (SBP).

A researcher wants to test the effectiveness of a new drug to treat asthma. One hundred patients with chronic, stable asthma were randomly assigned to one of three groups to receive a placebo (0mg), 1mg of drug, or 5 mg of drug. After treatment, a doctor tested the patient’s forced expiratory volume for 1 second (FEV1). Which statistical test would be best to determine if there is a significant difference between groups? one-sample t-test dependent samples t-test independent samples t-test ANOVA
