The average amount of weight loss, in pounds, by 10 participants in a six-month weight-reduction program is 24.1 pounds. The median weight loss for these participants is 26.4 pounds. Using the empirical relationship among mean, median, and mode, estimate the mode and comment on the skewness of the distribution.
According to the Carnegie unit system, the recommended number of hours students should study per unit is 2. Are statistics students' study hours different from the recommended number of hours per unit? The data show the results of a survey of 15 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 0.4, 1.7, 0.8, 0.1, 0, 1.6, 3, 2.8, 3.2, 0.7, 0, 0.6, 1.2, 0, 0.9 What can be concluded at the a = 0.05 level of significance? a.

In a random sample of six mobile devices, the mean repair cost was $65.00 and the standard deviation was $11.50. Assume the population is normally distributed and use a t-distribution to find the margin of error and construct a 90% confidence interval for the population mean. Interpret the results.

.A study of 100 patients with back pain reported that the mean duration of pain was 12 months. It is known that the standard deviation of duration of back pain is 6.8 months. Assuming that the duration of this problem is normally distributed in the population; determine a 95% confidence interval for the mean duration of back pain in the population.
According to the Carnegie unit system, the recommended number of hours students should study per unit is 2. Are statistics students' study hours more than the recommended number of hours per unit? The data show the results of a survey of 15 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 0.7, 4.1, 0.6, 4.4, 3.2, 0.8, 3.1, 3.8, 1.1, 3.3, 2.1, 1.5, 2.5, 2.3, 1.7 What can be concluded at the αα = 0.01 level of significance? For this study, we should use The null and alternative hypotheses would be: H0:H0: H1:H1: The test statistic = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is αα Based on this, we should the null hypothesis. Thus, the final conclusion is that ... The data suggest that the population mean study time per unit for statistics students is not significantly more…
A nutritionist wants to determine how much time nationally people spend eating and drinking. Suppose for a random sample of 1088 people age 15 or older, the mean amount of time spent eating or drinking per day is 1.74 hours with a standard deviation of 0.54 hour. Determine and interpret a 95% confidence interval for the mean amount of time Americans age 15 or older spend eating and drinking each day.
A special diet was given to a species of birds and the gain in weight (in grams) over a 5-week period was measured. The following are the summary statistics for a random sample of 30 birds: 5-number summary: 55, 90, 105, 120, 155.What is the most likely shape of the distribution?
Suppose that water usages in American showers are normally distributed, with an average shower using 16.4 gallons, and a standard deviation of 3.7 gallons. Estimate the percentage of showers that used between 9 and 23.8 gallons more than 27.5 gallons less than 12.7 gallons between 9 and 20.1 gallons
A sample of 22 public high school students spent an average of 7 hours studying per week. Assuming the distribution of hours spent studying is normally distributed. Find a 95% confidence interval for the mean number of hours spent studying by public high school students.? Assume the standard deviation is 1.3 hours.
