It is well know that IQ scores are mean IQ score is x = 109.7 with a standard deviation s approximately normal. (a) Compute a 95% confidence interval for the true population standard deviation for all TTU students, OTTU• (b) The true standard deviation of IQ scores for all adults is OALL = 15. Does it appear that the true standard deviation for TTU students differs from the true standard deviation for all adults? Explain.

Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is 4 inches. The heights of 6 randomly selected students are 69, 62, 68, 64, 61 and 68. x¯ = Margin of error at 99% confidence level = 99% confidence interval = [ , ]
A simple random sample from a population with a normal distribution of 97 body temperatures has x=98.20°F and s=0.63°F. Construct a 99% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
Suppose the mean height in inches of all 9th grade students at one high school is estimated. The population standard deviation is 3 inches. The heights of 7 randomly selected students are 72, 61, 74, 68, 64, 66 and 64. x¯ = Margin of error at 95% confidence level = 95% confidence interval = [ , ]
A study of B.A. (Hons.) Economics examination results of 1000 students in 1990 gave the mean теаn grade as 78 and the standard deviation as 8.0. A similar study in 1995 revealed the mean grade of the group as 80 and the standard deviation as 7-6. In which year was there the greater (i) absolute dispersion, (ii) relative dispersion ? What can we say about the average performance of the students over time?
A researcher collected sample data for 19 middle-aged women. The sample had a mean serum cholesterol level (measured in milligrams per one hundred milliliters) of 190.3, with a standard deviation of 9.5. Assuming that serum cholesterol levels for middle-aged women are normally distributed, find a 95% confidence interval for the mean serum cholesterol level of all women in this age group. Give the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit= Upper limit=
A simple random sample from a population with a normal distribution of 106 body temperatures has x=98.50°F and s=0.64°F. Construct a 98% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
A simple random sample from a population with a normal distribution of 98 body temperatures has x=98.40°F and s=0.68°F. Construct a 90% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
A researcher collected sample data for 10 women ages 18 to 24. The sample had a mean serum cholesterol level (measured in mg/100 mL) of 188.4, with a standard deviation of 5.7. Assuming that serum cholesterol levels for women ages 18 to 24 are normally distributed, find a 99% confidence interval for the mean serum cholesterol level of all women in this age group. Then find the lower limit and upper limit of the 99% confidence interval.
