Calculate the z-score for the largest value and interpret it in terms of standard deviations. Do the same for the smallest value N: 50 Mean:28.766 SE Mean: 0.476 St.Dev: 3.369 Min: 21.300 Q1: 26.375 Median: 29.400 Q3: 31.150 Max: 35.100
Calculate Z-score and Probabilty We have collected data on the total number of minutes people spent in the local emergency room. The times follow a normal model with a mean of 166.9 min and a standard deviation of 55.4 minutes. Find the following: What percent of ER patients spent between 2.5 and 3.5 hours there?
iger 2. Hypothesis: College students sleep less than the recommended 8 hours. Data: Sample mean (X) = 7.25, sample standard deviation (Sx) = 2.1, N = 25.
Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than 24 miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of miles driven is 23.4. The population standard deviation is 4.1 miles. At a = 0.01, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the critical value method with tables. Part 1 of 5 State the hypotheses and identify the claim with the correct hypothesis. H: u = 24 not claim Η: μ 24 claim The hypothesis test is a one-tailed test. Part: 1/5 Part 2 of 5 Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s):
Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than 24 miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of miles driven is 22.5. The population standard deviation is 4.1 miles. At a = 0.01, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the P-value method with a graphing calculator. Part: 0 / 4 Part 1 of 4 (a) State the hypotheses and identify the claim. H,: (Choose one) ▼ O
The distribution of heights in a population of women is approximately normal. Sixteen percent of the women have heights less than 62 inches. About 97.5% of the women have heights less than 71 inches. Use the empirical rule to estimate the mean and standard deviation of the heights in this population. Mean: K inches Standard Deviation: inches
Weights of whole walnuts are normally distributed with mean 9.2 grams and standard deviation 0.104 grams. What proportion of walnuts weigh less than 8.9722 grams? What proportion of walnuts weigh more than 9.0315 grams? Use the closest value in the normal table, and show all four decimals.

The speed vehicles traveled on a local highway was recorded for one month. The speeds ranged from 47 mph to 62 mph with a mean speed of 55 mph and a standard deviation of 6 mph. The quartiles and median speeds were 50 mph, 59 mph, and 52 mph. Suppose increased patrols reduced speeds by 7%. Find the new mean and standard deviation. Express your answer in exact decimals. Choose the best answer below: A. Mean: 3.85 mph, SD: 0.42 mph B. Mean: 58.85 mph, SD: 6.42 mph C. Mean: 51.15 mph, SD: 6 mph D. Mean: 58.85 mph, SD: 6 mph E. Mean: 51.15 mph, SD: 5.58 mph
After 84 students at a particular university take a psychological evaluation, the sample mean score on the test is calculated to be 117 with a standard deviation of 44. We are interested in testing whether or not the mean score of the students at this university is different than the published population average of 112. Calculate the value of the test statistic and then use that to determine the appropriate p-value. 0.5952 0.2976 0.1488 0.8512 1.7024 0.1488 0.0744
