Astigmatism is measured in diopters. A perfect eye with no astigmatism has 0 diopters while people with a measurement of 1.5 or more typically need contacts or eyeglasses to have clear vision. A sample of 50 students with glasses determined their level of diopters. The sample mean is found to be 1.795 diopters with a sample standard deviation of 0.356. Determine if this is significantly more than as compared to the typical measurement of 1.5 diopters.
In a factory the 95% confidence interval of the mean net weight of packed coffee was estimated based on a random sample of 50 packages. The standard deviation of the weights is unknown. The maximum error of the estimate is 0.8 grams. Give the standard error of the mean in grams.
Suppose the sediment density (g/cm) of a randomly selected specimen from a certain region is normally distributed with mean 2.65 and standard deviation 0.85. If a random sample of 25 specimens is selected, what would be the standard error of the mean?
Currently patrons at the library speak at an average of 60 decibels. Will this average decline after the installation of a new computer plug in station? After the plug in station was built, the librarian randomly recorded 61 people speaking at the library. Their average decibel level was 57.2 and their standard deviation was 7. What can be concluded at the the a = 0.10 level of significance?
To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 40 feet. Assume the population standard deviation is 4.9 feet. The mean braking distance for Make B is 44 feet. Assume the population standard deviation is 4.6 feet. At a = 0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. Complete parts (a) through (e). Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. (a) Identify the claim and state H, and Ha. What is the claim? A.
