  1. T-Test:
    1. In the case of the t-test, we assume that samples reflect the underlying distributions. But what is the underlying assumption about the distributions when the two sample t-test is used?
    1. what is the null hypothesis in the case of the two sample t-test?
    1. Explain what effect the magnitude of the variance has on the confidence interval.

Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the endpoints of the t-distribution with 2.5% beyond them in each tail if the samples have sizes n1=16 and n2=23. Enter the exact answer for the degrees of freedom and round your answer for the endpoints to two...

1.If the null hypothesis in a t-test for two samples is not rejected, what conclusion can be drawn about the two means of the categorical variable? 2. . Assume you collected larger samples of individuals to test your null hypothesis in question #1. Specifically, the sample sizes increased to 200 subjects in each group. Do your results and conclusions change from the test of the smaller sample sizes? (You must show your work).

Assume that both samples are independent simple random samples from populations having normal distributions. 4) A researcher obtained independent random samples of men from two different towns. She recorded the weights of the men. The results are summarized below: Town A Town B n1= 41 n 2 = 21 x1 = 165.1 lb x2 = 159.5 lb s1 = 34.4 lb s2 = 28.6 lb Use a 0.05 significance level to test the claim that there is more variance in...

Which of the following is a benefit to using a one-tailed t-test (as opposed to a two-tailed test)? A) It improves the predictive power of the independent samples t-test. B) It reduces the impact of within-groups variance. C) We are more likely to reject the null hypothesis when the null hypothesis is false. D) We are less likely to reject the null hypothesis when the null hypothesis is false.

What's the deal with differences? No unread replies.No replies. Suppose that random samples of college freshman are selected from two universities - 15 students from school A and 20 students from school B. On a standardized test: The sample from school A has an average score of 1000 with a standard deviation of 100. The sample from school B has an average score of 950 with a standard deviation of 90. (Assume the test scores came from normal distributions in...

Suppose that we want to test the null hypothesis that the mean of population 1 is equal to the mean of population 2. We select a random sample from population 1 and a random sample from population 2, and these two samples are independent. Circle the FALSE statement. A. We need to perform a two-sided test. B. If we know the variance of each population, even if they are different, we can use the Z test. That is, the test...

In the above hypothesis test in Q1, t-statistics test reject the null hypothesis, 40 is not within the confidence interval, but p value is smaller than the significance level alpha, how to explain this inconsistency? a. Sample size is too large. b. Sample size is too small. c. Mistake in calculation when you do the hypothesis test d. The dataset collected has low quality

t-Test for One Sample Mean 1. Let’s assume that lab rates require an average of 32 trials in a complex water maze before reaching a criterion of three consecutive error-less trials. To determine whether a mildly adverse stimulus has any effect on performance, a sample of 7 lab rats were given a mild electric shock just before each trial. Given research results that show a sample mean of 34.89 and a sample standard deviation of 3.02, test the null hypothesis...

When we compute an independent-samples t-test, we are looking to see if there are significant differences between the means of two independent groups, each measured on a different level of the independent variable. True or False When we compute a paired-samples t-test, we are looking to see if there are significant differences between the means of two independent groups, each measured on a different level of the independent variable. True or False If the p-value is > than 0.05, the...
