Two diets were given to samples of pigs over a period of time, and the following weight gains (in lbs) were recorded

Diet A 8, 4, 14, 15, 11, 10, 6, 12, 13, 7

Diet B 7, 13, 22, 15, 12, 14, 18, 8, 21, 23, 10, 17

Suppose we assume the normal regression model for these data.

(a) Carry out a one-way ANOVA to test for a difference between the conditional means of Y given Diet.

b) Construct 0.95-confidence intervals for differences between the means

With all the fad diets advertised on TV, a researcher wanted to know if there was a significant difference in weight loss depending on which new fad diet you were on. Over the course of 2 weeks, a total of 12 male volunteers who weighed the same and had similar lifestyles were broken up into 3 groups: Diet 1, Diet 2, and Diet 3. Conduct an ANOVA on the following table with alpha = 0.5 to determine if at least...

1A) An experiment was designed to estimate the mean difference in weight gain for pigs fed ration A as compared with those fed ration B. Eight pairs of pigs were used. The pigs within each pair were litter-mates. The rations were assigned at random to the two animals within each pair. The gains (in pounds) after 45 days are shown in the following table. Assuming weight gain is normal, find the 95% confidence interval estimate for the mean of the...

Twenty laboratory mice were randomly divided into two groups of 10. Each group was fed according to a prescribed diet. At the end of 3 weeks, the weight gained by each animal was recorded. Do the data in the following table justify the conclusion that the mean weight gained on diet B was greater than the mean weight gained on diet A, at the α = 0.05 level of significance? Assume normality. (Use Diet B - Diet A.) Diet A...

A study was conducted in order to compare the weight loss for two diet plans, Plan A and Plan B. Two hundred dieters were randomly selected. Of this sample 100 were placed on the Plan A diet and the remaining 100 were assigned to the Plan B diet. After the dieters were on the diet for 2 months the average weight loss and sample standard deviation of the weight losses were recorded. For the Plan A group there was an...

Electrobat, a battery manufacturer, is investigating how storage temperature affects the performance of one of its popular deep-cell battery models used in recreational vehicles. Samples of 30 fully charged batteries were subjected to a light load under each of four different storage temperature levels. The hours until deep discharge (meaning ≤ 20% of charge remaining) were measured. The data is shown in the accompanying table. 0 degrees F (hrs to discharge) 30 degrees F (hrs to discharge) 60 degrees F...

A study was conducted to investigate the effectiveness of three different methods to lower the blood pressure of individuals diagnosed with high blood pressure. The researcher was interested in the reduction of diastolic blood pressure in the subjects that were assigned to three groups. The first group took medication, the second group engaged in daily aerobic exercises, and the third group was prescribed a plant-based diet. The subjects were placed in their regiments for four weeks. Diastolic blood pressure was...
