Vhich of the following statements are true concerning the mean of the differences between two dependent samples (matched pairs)? elect all that apply. ]A. The methods used to evaluate the mean of the differences between two dependent variables apply if one has 62 weights of voters from Ohio and 62 weights of vot B. If one has twenty matched pairs of sample data, there is a loose requirement that the twenty differences appear to be from a normally distributed population. C. The requirement of a simple random sample is satisfied if we have dependent pairs of convenience sampling data. I D. If one wants to use a confidence interval to test the claim that H, >0 with a 0.05 significance level, the confidence interval should have a confidence level of 90%. 1E. If one has more than 2 matched pairs of sample data, one can consider the sample to be large and there is no need to check for normality.

Specifically, the researcher intends to know if the pulse rate will increase,decrease, or remain unchanged after a patient takes the medication. Thirty female asthmaticpatients of the same age were subjected to the experiment. It is known that the average pulserate for this population is 82 beats per minute. The pulse rate of each patient after taking themedication was recorded. The appropriate null and alternative hypotheses for the givenexperiment is ___________.A. Ho: μ ≥ 82 B. Ho: μ = 82 C.

A school administrator wants to see if there is a difference in the number of students per class for the Portland Public School district (Group 1) compared to the Beaverton School district (Group 2). Let be the average number of students per class for the Portland Public School district. Let ₂ be the average number of students per class for the Beaverton School district. Assume the populations are normally distributed. A random sample of 25 Portland classes found a mean of 38 students per class with a standard deviation of 3. A random sample of 28 Beaverton classes found a mean of 35 students per class with a standard deviation of 4. a. Find a 95% confidence interval for the difference of the means. Use Excel Two Means Calculator found in the Course and round answers to 2 decimal places. <1-1₂< b. Select the correct conclusion based on the above confidence interval. Since the above confidence interval gives only negative values, we have 95% confident that the average number of students…
The next test is a t-test for unequal variance. Here is the problem: The human resources department at Sue, Grabitt, and Runne also tracks the cost of one-bedroom apartments in two popular neighborhoods, NoBo and SoBo. The general perception of long-time residents is that rents are probably lower in SoBo. They hope to determine whether the average rent for a one-bedroom apartment is lower in SoBo than in NoBo. The results of their survey are shown in Tables 18 and 19: Step 2. Select the Level of Significance, α A 5 percent significance has been selected. Step 3. State the Null Hypothesis (H0) and Alternate Hypothesis (H1) H0: H1: Step 4. Compose the Decision Rule Step 5.

When two births are randomly selected, the sample space for genders is bb, bg, gb, and gg. Assume that those four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births. Does the mean of the sample proportions equal the proportion of girls in two births? Does the result suggest that a sample proportion is an unbiased estimator of a 1 1 population proportion? For the entire population, assume the probability of having a boy is the probability of having a girl is, and this is not affected by how many boys or girls have previously been born. Determine the probabilities of each sample proportion. Sample proportion of girls ▼ ▼ ▼ Probability (Type integers or simplified fractions.)
