Assume that the weight loss for the first month of a diet program varies between 6 pounds and 12 pounds, and is spread evenly over the range of possibilities, so that there is a uniform distribution. Draw a graph to represent this uniform distribution. Find the probability of the given range of pounds lost. Points: 5 20) Find the probability of weight loss less than 7 pounds. Show your work below. Graph Probability

Wildlife conservationists studying grizzly bears in the United States found that the mean weight of 23 adult males was 629 pounds with a standard deviation of 90 pounds. Construct a 90% confidence interval for the mean weight of all adult male grizzly bears in the United States. Assume that the weights of all adult male grizzly bears in the United States are normally distributed. Round to the nearest whole number.

A group of researchers investigated the impact of every-other-day fasting on weight loss in humans. After 22 days of every-other-day fasting, the researchers measured the amount of weight that was lost by each of 16 human subjects. These data were used to construct a 95% confidence interval for predicting the mean weight loss for the population of people who followed the every-other-day fasting diet for 22 days. The computed interval was (3.4, 4.8) pounds. The interpretation of the interval given...

An experiment was conducted to test the effect of a new dietary supplement for weight loss. Ten men and 10 women were given the supplement daily for a month, then the amount of weight each person lost was determined. A significance test was conducted at the ? = 0.05 level for the difference in the means of the number of pounds lost between men and women. The test resulted in t = 2.178 and p = 0.03. If the alternative...

An advertisement for a popular weight-loss clinic suggests that participants in its new diet program lose, on average, more than 10 pounds. A consumer activist decides to test the authenticity of the claim. She follows the progress of 18 women who recently joined the weight-reduction program. She calculates the mean weight loss of these participants as 10.8 pounds with a standard deviation of 2.4 pounds. Which of the following are appropriate hypotheses to test the advertisement's claim? Multiple Choice Ho:u...
