A professor wants to know which type of instructional mode students had more satisfaction. The professor randomly selected n = 5 students from each of the following types of classes: online only, hybrid, and face-to face only. Student were given a satisfaction survey. Are their differences in student satisfaction among the different instructional modes. The data are below: Online Hybrid Face-to-Face 3 3 4 3 3 1 3 1 3 2 2 2 2 1 3 Calculate the F statistic.

A tutor who teaches four tutorials is interested in exploring whether certain colours are better than others for student learning. To test this, she designed an experiment to see whether different colour PowerPoint slides impact students’ final exam grades. Each of the tutor’s four tutorials were presented with a different colour background in the PowerPoint slides throughout the semester (red, blue, yellow or green). The average final exam grade for each class was measured. What test would the tutor use to determine whether there were any differences in final exam grades between the classes? One-way independent groups ANOVA Repeated measures ANOVA Pearson's correlation Independent groups t-test

A random sample of 200 new vehicle buyers were asked to respond to a survey about what kind of vehicle they purchased. One question, summarized in the table below, asked each respondent to choose the vehicle that best described the type of vehicle that they purchased. The vehicle choices were car, pick-up, sport utility vehicle, van, or other.

Compute the linear correlation coefficient between MRI count and IQ for both the males and the females. Do you believe that MRI count and IQ are linearly related? The linear correlation coefficient for females is. The linear correlation coefficient for males is. (Round to three decimal places as needed.) Are MRI count and IQ linearly related? linear The linear correlation coefficient for females is close to ▼so relation exists between MRI count and IQ for females. The linear correlation coefficient for linear relation exists between MRI count and IQ males is close to for males. SO
Professors collected data consisting of eye color and gender of statistics students. Among 912 male students, 276 had blue eyes. Among 1102 female students, 372 had blue eyes. Use a 0.01 significance level to test the claim that the proportions of blue eyes are the same for males and females. Complete parts (a) through (c) below. Consider the first sample to be the sample of males and the second sample to be the sample of females. O D. Ho: P₁ = P₂ H₁: P₁ P₂ Identify the test statistic.
