Does When Food Is Eaten Affect Weight Gain? A study was introduced that examined the effect of light at night on weight gain in mice. In the full study of 27 mice over a four-week period, the mice who had a light on at night gained significantly more weight than the mice with darkness at night, despite eating the same number of calories and exercising the same amount. Researchers noticed that the mice with light at night ate a greater percentage of their calories during the day (when mice are supposed to be sleeping). The computer output shown below allows us to examine the relationship between percent of calories eaten during the day, DayPct, and body mass gain in grams, BMGain. A scatterplot with regression line is also shown below. Pearson correlation of BMGain and DayPct = 0.740 P-Value = 0.000 The regression equation is: BMGain = 1.113 + 0.127DayPct Predictor Coef SE Coef T P Constant 1.113 1.382 0.81 0.428 DayPct 0.12727 0.02315 5.50 0.000 S = 2.23097 R-Sq = 54.7% R-Sq(adj) = 52.9% (a) What is the correlation between these two variables? What is the p-value from a test of the correlation? (b) What gain is predicted for a mouse that eats 55% of its calories during the day (DayPct = 55)? Round your answer to two decimal places. (c) What is the estimated slope in this regression model? Round your answer to three decimal places.

Consider an experiment in which adult laboratory mice were fed one of three diets: high fat, low fat, and a control diet. The mice were weighed, received these diets for 2 weeks, and then were weighed again. The table below shows the results of the experiment. Diet Gained weight Lost weight High Fat 79 21 Low Fat 30 69 Control 70 30 What proportion of mice in the experiment gained weight? Group of answer choices 0.90 0.60 0.40 0.80

A study was conducted in which mice that had a dim light on at night (rather than complete darkness) ate most of their calories when they should have been resting: These mice gained a significant amount of weight; despite eating the same number of calories as mice kept in total darkness The time of eating seemed to have a significant effect There were 10 mice in the group with dim light at night and they gained an average of 7.9 g with a standard deviation of 3.0. We see in Figure that the data are not heavily skewed and do not [ have extreme outliers_ Figure 1 Body mass gain (in grams) for mice with a night light Use the t-distribution to find a 90% confidence interval for weight gain. Round your answers to two decimal places: The 90% confidence interval is
