In a random sample of 25 people, the mean commute time to work was 31.6 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 98% confidence interval for the population mean u. What is the margin of error of u? Interpret the results. The confidence interval for the population mean u is ( D (Round to one decimal place as needed.)

A teacher administers a standardized math .4 test to his class of 75 students. the mean score (out of 300 possible points) is 235. from previous studies, you know the population standard deviation is 28. using the sample data given, calculate a 95% confidence interval for the population mean (235.9 ,234.1) O (243.3 ,226.7) O (241.3 ,228.7) O (237 ,233) O (300 ,200) O
If a 90% confidence interval for the mean is (75.3 to 80.9), we would reject H0:  =70 in favor of H1:  ≠ 70 at  = 0.05.
The mean weight of trucks traveling on a particular section of I-475 is not known. A state highway inspector needs to estimate the population mean. He selects and weighs a random sample of 49 trucks. The mean weight of the 49 trucks was 15.8 tons. Assume for purposes of this problem that the population standard deviation is known, and it is 3.8 tons. What is the 72% confidence interval for the population mean? a. 15.2 and 16.4 b. 14.7 and 16.9 c. 16.1 and 18.1 d. 13.8 and 15.6
Suppose we gather a random sample of 20 data points. Assume the population standard deviation is 11. If the average of the data points was 23, what is a 90% confidence interval for the mean, μμ? Round to the nearest hundredth.
The distribution of study times for first year students follows a Normal distribution with standard deviation σ = 78 minutes. Suppose a sample of 452 students found that the mean study time for these students was x¯= 192 minutes per week. Use this to find a 95% confidence interval to estimate the mean study time for all students. We are 95% confident that the mean study time for first year students is between _____minutes and _____ minutes
The distribution of study times for first-year students follow a Normal distribution with a standard deviation σ = 78 minutes. Suppose a sample of 431 students found that the mean study time for these students was x¯= 195 minutes per week. Use this to find a 95% confidence interval to estimate the mean study time for all students. We are 95% confident that the mean study time for first-year students is between (Answer) and minutes ( Answer) minutes.
From a sample of 38graduate students, the mean number of months of work experience prior to entering an MBA program was 34.93. The national standard deviation is known to be 18 months. What is a 95% confidence interval for the population mean? 95% confidence interval for the population mean is _____ , _____. (Use ascending order. Round to two decimal places as needed.)
#2 A sample of 64 airplanes gave a mean air time (time spent flying) of 49 hours. If the standard deviation is 14.8 hours, construct a 90% confidence interval for u, the true mean air time.
A sample of 30 days of sales were taken. The mean of those 30 days of sales were $10,000 with a standard deviation of $2,000 a. Get a 95% confidence interval for the mean of sales for all days. How many additional sales days would you need to sample to reduce the margin of error to $500?
Mrs. Gallas wanted to estimate the average weight of an Oreo cookie to determine if theaverage weight was less than advertised. She selected a random sample of 30 cookies andfound the weight of each cookie (in grams). The mean weight was = 11.1921 grams with astandard deviation of sx = 0.0817 grams. Make a 95% confidence interval to estimate the truemean weight of an Oreo. 1. What is the formula for calculating the standard deviation of the sampling distribution of x? 2.What condition must be met to use this formula? Has it been met?
Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
You want to buy a washing machine, and a salesperson tells you that the mean repair costs for Model A and Model B are equal. You research the repair costs. The mean repair cost of 21 Model A washing machines is $215. Assume the population standard deviation is $19. The mean repair cost of 22 Model B washing machines is $221. Assume the population standard deviation is $20. At α=0.01, can you reject the salesperson's claim? Assume the samples are random and independent, and the populations are normally distributed.
