An instructor wants to know if the color of the text on her handouts may impact student learning. They take a small random sample of students enrolled in their university and randomly assign each student to one of three groups: black text, blue text, or yellow text. Each participant receives a handout, with the respective text color. After studying for 5 minutes, they are given an assessment. Their scores on that assessment follow:

Black text- 19, 17, 16, 15, 13

Blue text- 18, 16, 15, 15, 11

Yellow text- 15, 13, 13, 10, 9

A. Use the six step hypothesis testing procedure to determine if there is evidence that the population means are different. You may do the calculations by hand, or you can use JASP. If you use JASP, show your work by including a screenshot of your JASP output. Use the standard 0.05 alpha level. (Please don't write cursive script)

Step 1: Identify the population, comparison distribution, and assumptions

Step 2: State the null and research hypotheses

H0:

H1:

Step 3: Determine the characteristics of the comparison distribution (shape, mean, & standard error)

Step 4: Determine the critical values

Step 5: Calculate the test statistic.

Step 6: Make a decision (reject/fail to reject + real world conclusion)

B. Summarize the results of your one-way ANOVA in one sentence in APA format

Bernice, a local entrepreneur, wants to know if the color of her hand-made coffee mugs were equally preferred by northern and southern customers. She focused on just 2 color types (red, blue) and divided customers based on living in the north or south of the United States. She then simply kept track of how many blue and red mugs were sold to southern and northern customers.

An advertising company wants to know whether the size of an advertisement and the color of the advertisement make a difference in the response of magazine readers. A random sample of readers shown ads of 4 different colors and 3 different sizes. Assume that the ratings follow the normal distribution. The rating is shown in the following table: Size of Ad Color of Ad Red Blue Orange Green Small 4 3 3 8 Medium 3 5 6 7 Large 6...

1. An instructor would like to examine the effect of using handouts during lecture on student’s grades. Usually no handouts are used and the mean final grade in the class is μ = 80. This semester, the instructor uses handouts during lecture and the mean final grade in the class of n = 41 students is M = 82.5 with a standard deviation of s = 6. a. Is there sufficient evidence to conclude that handouts significantly (α = .01)...

A STAT 200 instructor wants to know if students tend to score differently on the lesson 4 and 5 quizzes. Data were collected from a representative sample of 60 students during the Summer 2018 semester. Data were paired by student. The mean difference, computed as Lesson 4 Quiz – Lesson 5 Quiz, was 0.3833 points with a standard deviation of 1.9891 points. A. Explain why it is appropriate to use the t distribution to approximate the sampling distribution in this...

A STAT 200 instructor wants to know if more than half of online students use the eTextbook. Conduct a randomization test given that 80 students in a random sample of 120 use the eTextbook. A. Determine what type of test you need to conduct and write the hypotheses. B. Construct a randomization distribution under the assumption that the null hypothesis is true. Take at least 5000 resamples. C. Use the randomization distribution to find the p-value. D. Decide if you should...

A fitness instructor wants to understand the relationship between her heart rate during a workout and the calories burned per minute during the workout. She recorded these two measurements over the course of several workouts. StatCrunch was used to create the output below: For any numeric responses, round your answers to four decimal places. Use the regression equation to provide a point estimate for a workout when the average heart rate is 150 beats per minute: y = The fitness...

A psychiatrist wants to know what the impact of using a specific grounding technique will be on his patients who have panic attacks. Dr Lessanxious divided his patients into two groups. One group of patients was taught to use the specific grounding technique and the second group was not taught the grounding technique. After being taught the grounding technique (or not) all patients were asked to rate the intensity of their panic attacks on a scale of 1-20 with higher...

A criminology professor wants to know the impact of the type of course delivery. Their current class is a hybrid, consisting of 22 students. The average this semester was 84.1 with an SS of 158.76. The past semester’s class, taught in a traditional face to face format, had an n = 17 and an average performance in the class was a 78.2 with an SS of 160.35. Test the hypothesis that the current class has a higher average than the...

Randi wants to know if at least 90% of the employees at her company are currently enrolled in a health insurance plan. She randomly samples 700 employees and finds that 651 of them are currently enrolled in a plan. Randi conducts a one-proportion hypothesis test at the 5% significance level, to test whether the true proportion of employees enrolled in a plan at this company is greater than 90%. For this test: H0:p=0.9; Ha:p>0.9, which is a right-tailed test. Use...
