(B)The mean of sample 1 is equal to the mean of sample 2. (C)The sample mean is greater than the population mean. (D)The sample mean is equal to the population mean.
State which hypothesis test would be appropriate under the following conditions. Our data set’s mean is being compared to a fixed or assumed value. The data set comes from a population that has a normal distribution and we know the population standard deviation. Group of answer choices 1--- z-test 2---- Mann-Whitney U Test 3----- 2-sample t-test with unequal variances 4--- t-test 5---- 2-sample t-test with equal variances I just need to know which of the 5 is the right answer....
1. You want to test whether you can reject the null hypothesis that a population mean is greater than or equal to 10. To do this, you collect a random sample of size 500 from the population, and you calculate that the sample mean and sample standard deviation are 8.6 and s, respectively. Which of the following is true? a. If s is any value between 11 and 13, you can reject the null hypothesis at the 5% significance level....
The null hypothesis in an independent-samples t-test would be stated as which of the following: (A) The mean of the sample is equal to the mean of the population. (B) The mean of sample 1 is equal to the mean of sample 2. (C) The mean of sample 1 is not equal to the mean of sample 2. (D) The mean of the sample is not equal to the mean of the population
1. Conduct a test of the null hypothesis that the mean height for all students in the Census at School database is equal to 155 cm vs the alternative that the mean Height is greater than 155 cm. Use a significance level of 0.05. a. State the null and alternative hypotheses. Ho: m = 155 Ha: m > 155 b. Provide the Statcrunch output table. Hypothesis test results: Variable Sample Mean Std. Err.

Identify the Null and Alternative Hypotheses for an Experiment With One Population Mean Question A hospital claims that the mean wait time for emergency room patients is at least 55 minutes. A group of researchers believe that this is not accurate, and want to show that the mean wait time is less than 55 minutes. Identify the group's null hypothesis, Ho. and the alternative hypothesis, Ha, in terms of the parameter u Select the correct answer below: Ho: >55; H:...
