The number of times a toggle switch made by the Acme company can be switched between the on and off position before failure is believed to be normally distributed. Until now, it was always assumed that the mean number of toggles before failure was 1750. The quality lab at Acme contemplates buying a new machine for making the switches because it wants to have the switches last longer before failing. Acme has the option of using the new machine for two weeks (without an obligation to buy) before committing to it --they will have to pay considerable money to buy the machine and only want to do so if they are convinced it is better. They plan to take a sample of switches using the new machine while it is on trial and compute its mean and standard deviation for computing a test statistic. The correct hypotheses for this test, given the above would be: A: H,:x=1750 vs. H,:x>1750 B: Н.:х3D1750 vs. H.:x<1750 C: Ho:u=1750 vs. H.:u>1750 D: H,:u=1750 vs. Ho:u<1750 E: H:u=1750 vs. Ho:µ#1750

For each problem, write which test you used in your calculator, draw the graph, calculate pvalue, and write your conclusion in a complete sentence. A simple random sample of 41 8th grade students found that the mean score on an exam is 250 with a sample standard deviation of 55. The school administration claims that the population mean for the school is less than 265. Is there enough evidence to support the claim?
During one shift, the express lane clerk recorded how many times customers violated the "10 items or less" rule for his lane. In particular, he recorded how many items over the limit each violator placed on the conveyor belt. This data is summarized in the histogram below. NOTE: The last class actually represents "7 or more items," not just 7 items. Frequency 12+ 298 ans = 10- a 2 0.5 1.5 2.5 3.5 4.5 5.5 6.5 7.5 # items over 10 What is the frequency of times the limit was exceeded by at least 3 items?

Suppose that a polling company surveyed 600 people about how much time they spend watching television each day. The results of this survey were compiled and used to create this relative frequency histogram. Assume that all percentages shown in the histogram are whole numbers. Each of the bars in this histogram includes only the left endpoint of the class except for the last bar, which also includes the right endpoint. What percentage of respondents said that they watch television at least six hours per day? How many respondents said that they watch television between three and five hours per day?

A researcher who studies mental health is interested in the length of time (in days) that a patient stays in the hospital after they have presented to emergency having suicidal ideation. The researcher follows the first 30 patients during the month of January and follows them until each one of them is released. Below is the histogram of the data obtained from the 30 patients. 1. What is the shape of this distribution and please construct a frequency table. Given the shape and type of data, which measure of central tendency would you be more likely to report? Why?
