The following table was generated from the sample data of 10 junior high students regarding the average number of hours they are unsupervised per night, the average number of hours they play video games per night, and their final grades in their math class. The dependent variable is the final grade, the first independent variable (\(x_1\)) is the number of hours unsupervised each night, and the second independent variable (\(x_2\)) is the number of hours of video games each night.| | Coefficients | Standard Error | t-Stat | p-value ||--------------------------|--------------|----------------|----------|----------|| Intercept | 62.711817 | 4.607133 | 13.611896| 0.000010 || Hours Unsupervised | 0.635048 | 0.915495 | 0.693666 | 0.513836 || Hours Playing Video Games| 7.528738 | 1.296727 | 5.805955 | 0.001145 |**Step 1 of 2:** Write the multiple regression equation for the computer output given.

In a 4 point grade system, an A is worth 4 points, a B is worth 3 points, a C is worth 2 points and a D is worth 1 point. No points are awarded for an F. Last semester Tanya received a B in a 4 credit hour course, an A in a three credit hour course, a C in a three credit hour course, and an A in another three credit hour course. Grade point average (GPA) is calculated as a weighted average using the credit hours as weights and the number of points corresponding to the grades as pieces of data. Calculate Tanya's GPA for the previous semester. Round your answer to the nearest hundredth and explain in complete sentences your process. Show all work.
You are an education researcher interested in studying if race or ethnicity affects the severity of punishment children receive. Through open records, you are able to collect from several high schools the length of suspensions given to kids for fighting along with the race/ethnicity of the child. The state of Texas divides school children into one of 7 race/ethnicity groups: African American, American Indian, Asian, Hispanic, Pacific Islander, White, or Multiracial. You want to compare the average length of suspension among these 7 groups. Which statistical test would be best to determine if there is a significant difference in the severity of punishment among the different groups? one-sample t-test related samples t-test independent samples t-test ANOVA

The owner of a chain of mini-markets has two stores, Store 1 and Store 2, in one city. She recently added a breakfast station in Store 1 and wants to determine if the mean daily sales of Store 1 is greater than the mean daily sales of Store 2. After choosing 12 days at random, she records the sales (in dollars) at Store 1 for these days. Then, she records the sales at Store 2 for these same days. The data and the differences (Store 1 minus Store 2) are shown in the table below.

Suppose Laura, a facilities manager at a health and wellness company, wants to estimate the difference in the average amount of time that men and women spend at the company's fitness centers each week. Laura randomly selects 15 adult male fitness center members from the membership database and then selects 15 adult female members from the database. Laura gathers data from the past month containing logged time at the fitness center for these members. She plans to use the data to estimate the difference in the time men and women spend per week at the fitness center. The sample statistics are summarized in the table. Population Populationdescription Population mean(unknown) Samplesize Sample mean(min) Sample standarddeviation (min) 11 male μ1 n=15 x¯1=137.7 s=51.7 22 female μ2 n=15 x¯2=114.6 s=34.2 df=24.283 The population standard deviations are unknown and unlikely to be equal, based on the sample data.

Approval 2008. Of all the post–World War II presidents,Richard Nixon had the highest disapproval rating near theend of his presidency. His disapproval rating peaked at 66% in July 1974, just before he resigned. This percent-age has been considered by some pundits as a high water mark for presidential disapproval. However, in April 2008,George W. Bush’s disapproval rating peaked at 69%,according to a Gallup poll of 1016 voters. Pundits starteddiscussing whether his rating was discernibly worse thanthe previous high water mark of 66%. What do you think?
A high school teacher would like to examine his students’ exam scores based on seating arrangements. He assigned n = 15 students to sit in the last three rows of his class and n = 15 students to sit in the first three rows. Each student received a 45-minute lecture for one week and were given the same exam the following school day. The front row students had a mean of M = 78 with SS = 10.50 on their exam. And the back row students had a mean of M = 72 with SS = 8.90. Is there a significant difference in exam scores? Test with = .05.

Kris works for the MESA Air Pollution Study at UW, and studies the correlation be- tween air pollution and the disease atherosclerosis. Nationally, 40% of adults suffer from atherosclerosis. Kris suspects that the proportion of people with atherosclerosis in high- pollution areas is higher. In a random sample of 600 residents of high-pollution areas, he finds that 270 (45%) subjects have atherosclerosis. At the 1% level (α = .01), is this good evidence that people in high-pollution areas are more likely to have atherosclerosis? (a) Which of the following is the Ha ? (research claim or alternate) A. Ha : p ≥ 0.40 B. Ha : pb ≥ 0.40 C. Ha : p > 0.40 D. Ha : p > b 0.40 E. Ha : p > b 0.45 F. Ha : p > 0.45 G. Ha : pb ≥ 0.45 H. Ha : p ≥ 0.45 I.
