A study of a local high school tried to determine the mean number of text messages that each student sent per day. The study surveyed a random sample of 123 students in the high school and found a mean of 200 messages sent per day with a standard deviation of 66 messages. Determine a 95% confidence interval for the mean, rounding all values to the nearest whole number.

Suppose an electrical firm manufactures light bulbs that have a length of life that isnormally distributed, with a standard deviation of 55 hours. If a random sample of 27 bulbs has a mean length of life of 1,320 hours, find a 99% confidence interval for the population mean length of life of all bulbs produced by this firm. Interpret this interval.
A recent sample survey reports that 66% of 18-to 25-year-old consumers are comfortable sharing personal data with their communication service providers (CSPs). To conduct a follow-up study that would provide 99% confidence that the point estimate is correct to within ± 0.03 of the population proportion, how many 18-to 25-year-old consumers need to be sampled?
A random sample of 25 students from a large university yields a sample mean GPA of 2.71 with sample standard deviation 0.51. a) Constructa90%confidenceintervalforthetruemeanGPAofallstudentsattheuniversity. b) What is the 90% lower confidence bound on the true mean GPA?
An electrical firm manufactures light bulbs that have a length of life that is approximately normallydistributed with a standard deviation of 40 hours. If a sample of 30 bulbs has an average life of 780hours, find a 96% confidence interval for the population mean of all bulbs produced by this firm.
a sample of 17 college graduates resulted in a mean starting salary of $38,000 and a st. dev. of $1700. Assuming the starting salaries are normally distributed the 99% confidence interval for the mean starting salary of all college graduate is: (), ()
An electrical engineer wishes to compare the mean lifetimes of two types of transistors in an application involving high-temperature performance. A sample of 60 transistors of type A were tested and were found to have a mean lifetime of 1827 hours and a standard deviation of 168 hours. A sample of 180 transistors of type B were tested and were found to have a mean lifetime of 1658 hours and a standard deviation of 225 hours. Find a 95% confidence interval for the difference between the mean lifetimes of the two types of transistors.
A survey conducted by the AAA showed that a family of four spends on average $215.60 per day while on vacation. Suppose a sample of 64 families of four vacationing at Niagara Falls resulted in a sample mean of $252.45 per day with a sample standard deviation of $74.50. Develop a 98% confidence interval for the mean amount that a family of four visiting Niagara Falls will spend.
The trade magazine QSR routinely checks the drive-through service times of fast-food restaurants. A 95% confidence interval that results from examining 737 customers in Taco Bell's drive-through has a lower bound of 155.7 seconds and an upper bound of 160.9 seconds (a) What is the mean service time from the 737 customers?
The 95% confidence interval for the mean duration of imprisonment, μ, of all East German political prisoners with chronic PTSD is between 18.8 months and 48.0 months. (A) Find the sample size required to have a margin of error 12 months and a 99% confidence level. Assume that σ = 42 months. (B) Find the 99% confidence interval for the mean duration of imprisonment, μ, of all East German political prisoners with chronic PTSD if a sample of the size determined in part (a) has a mean of 36.2 months. Interpret the results.

An ecologist randomly samples 20 plants of a specific species and measures their heights. He finds that this sample has a mean of 17 cm and a standard deviation of 4 cm. If we assume that the height measurements are normally distributed, find a 90% confidence interval for the mean height of all plants of this species. Then find the lower limit and upper limit of the 90% confidence interval.
