A study of the amount of time it takes a hiker to hike to the bottom of the Grand Canyon and back to the top shows that the mean is 10 hours and the standard deviation is 2 hours. If 9 hikers are randomly selected, find the probability that their mean hiking time is less than 9 hours. P(x < 9 hours) = .

n a sample of 13 randomly selected high school seniors, the mean score on a standardized test was 1191 and the standard deviation was 167.0 Further research suggests that the population mean score on this test for high school seniors is 1020 Does the t-value for the original sample fall between minus−t 0.99t0.99 and t 0.99t0.99? Assume that the population of test scores for high school seniors is normally distributed. Question content area bottom Part 1 The t-value of tequals=enter your response here ▼ does does not fall between minus−t 0.99t0.99 and t 0.99t0.99 because t 0.99t0.99equals=enter your response here.
Confidence interval of the population mean is given by: X+2 x where X is the mean, s is the standard deviation and n is the sample size. Create a function called "summary" that lists mean, %15 trimmed mean and the 95% bounds of confidence interval for a random sample. Use the function to calculate the statistics for the given sample where x= (1200, NA, 1205, 1203, 1296,1304) 1. 2.

In a test of the effectiveness of garlic for lowering cholesterol, 43 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before - after) in their levels of LDL cholesterol (in mg/dL) have a mean of 3.3 and a standard deviation of 17.5. Construct a 95% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol? Click here to view a t distribution table.
