Which of the following is the null hypothesis? Highlight or circle your answer. [.5 points]
a) H0: µ1 = µ2
b) H1: µ1 = µ2
c) H0: µ1 ≠ µ2
d) H1: µ1 ≠ µ2
10b. Which of the following is the alternative, or research, hypothesis? Highlight or circle your answer. [.5 points]
a) H0: X1 = X2
b) H1: X1 = X2
c) H0: X1 ≠ X2
d) H1: X1 ≠ X2
11. Which test is needed to answer this question? Highlight or circle your answer. [.5 point]
a) one-sample t-test
b) one way ANOVA
c) independent samples t-test
d) dependent samples t-test
From the given information,
The required answers are,
10a. As null hypothesis contains "=" sign hence required answer is,
a) H0: µ1 = µ2
10b. As alternative hypothesis contains <,>,≠ sign hence required answer is,
d) H1: X1 ≠ X2
11. As on the title this is one sample test and test statistic is "t"
Hence, the required answer is,
a) one-sample t-test

Scenario 3. A 5th grade school teacher believes that she has an exceptionally gifted group of students in her class this year. She learns that the national average score on the 5th grade annual test is 150, with a standard deviation of 30. She wants to compare her student’s scores to the national average. 1. What is the null hypothesis for scenario 3? a. HO: µ1 = µ2 b. HO: µ1 = µ2 =µ3 c. r = 0 d. H0:...

2. Hypothesis Test for Two Populations including t-Test for μ1-μ1 t-Test for μd F-Test for Suppose we are comparing two population means, µ1 and µ2, and consider their difference, µ 1 - µ 2. If the alternative hypothesis contains the statement HA: µ 1 - µ 2 < 0, which of the following is an equivalent statement to HA? Group of answer choices a. µ1 is larger than µ2 b. µ1 is smaller than µ2 c. µ1 is the same...
Can taking chess lessons and playing chess improve memory? The online article described a study in which sixth-grade students who had not previously played chess participated in a program in which they took chess lessons and played chess daily for 9 months. Each student took a memory test (the Test of Cognitive Skills) before starting the chess program and again at the end of the 9-month period. The table below shows the results for 12 randomly selected students. Student 1...
A paired difference experiment produced the following data: nD = 18 x1 = 92 x2 = 95.5 xD = -3.5 sD2 = 21 Determine the values of t for which the null hypothesis, µ1 - µ2 = 0, would be rejected in favor of the alternative hypotheses, µ1 - µ2 < 0. Use α = .10. Conduct the paired difference test described in part a. Draw the appropriate conclusions. What assumptions are necessary so that the paired difference test...
Imagine that you wish to examine two sample means to decide if you can reject the hypothesis that µ1= µ2. The sample means are comprised of GPAs (grade point averages) that were collected from different, randomly chosen, students at two different universities. Which of the following types of tests should you use? Group of answer choices A z test A one-sample t test A paired-samples t test An independent-samples t test None of the tests listed above could be appropriate.
