You are interested in finding a 99% confidence interval for the average number of days of class that college students miss each year. The data below show the number of missed days for 15 randomly selected college students. Round answers to 3 decimal places where possible. 1 7 12 10 2 0 9 0 7 11 6 11 10 2 12 b. With 99% confidence the population mean number of days of class that college students miss is between ? and ? days. c. If many groups of 15 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About ? percent of these confidence intervals will contain the true population mean number of missed class days and about ? percent will not contain the true population mean number of missed class days.
In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and a sample of the results is listed below (1 = not attractive; 10 = extremely attractive). Construct a confidence interval using a 99% confidence level. What d the results tell about the mean attractiveness ratings of the population of all adult females? 7, 9, 3, 8, 5, 4, 8, 8, 7, 10, 5, 9 O What is the confidence interval for the population mean µ? <µ< (Round to one decimal place as needed.) What does the confidence interval tell about the population of all adult females? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The results tell nothing about the population of all adult females, because participants in speed dating are not a representative sample of the population of all adult females. O B. We are 99% confident that the interval from to actually contains the true mean attractiveness rating of all adult females.…
You were interested to know how long do students of mathematics in the university spend studying their math lessons in a day. You asked 10 random students and obtained the following data (in hours): 2, 1.5, 3, 2, 3.5, 1. 0.5, 3, 2, 4. Construct a 99% confidence interval for the average time that students spend studying math in a day. O 1.46 hours to 3.04 hours O none of the choices.

Question: Part B. Construct a 95% confidence interval of the mean pulse rate for adult males. __bpm <u<__bpm Multiple Choice: Compare the results. A. The confidence intervals do not overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males. B. The confidence intervals overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females. C. The confidence intervals do not overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males. D. The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
A genetic experiment with peas resulted in one sample of offspring that consisted of 448 green peas and 171 yellow peas. a. Construct a 95% confidence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations? Express the percentages in decimal form.
