To assess the precision of a laboratory scale, we measure a block known to have a mass of 1 gram. We measure the block n times and record the mean of the measurements. Suppose the scale readings are Normally distributed with unknown mean u and standard deviation o=0.001 g. How large should n be so that a 99% confidence interval for u has a margin of error of ±0.00001? O 54,103 O 10,000 O 258 O 66,358
A sample of size n=49 is drawn from a popular whose standard deviation is q=4.8. a. Find the margin of error for a 95% confidence interval for "u". b. If the sample size were n=60, would the margin of error be larger or smaller?
In a random sample of 24 people, the mean commute time to work was 33.1 minutes and the standard deviation was 7.3 minutes. Assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean µ. 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.) The margin of error of u is (Round to one decimal place as needed.) Interpret the results. O A. If a large sample of people are taken approximately 90% of them will have commute times between the bounds of the confidence interval. O B. With 90% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval. O C. It can be said that 90% of people have a commute time between the bounds of the confidence interval. O D. With 90% confidence, it can be said that the commute time is between the bounds of the confidence interval.
