The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six days after pouring. The data are as follows. Can you conclude that the mean strength after three days is greater than the mean strength after six days? Let μ1 represent the mean strength after three days and μd = μ1 - μ2.

The boiling point of 16 samples of a certain brand of hydrogenated vegetable oil used in a fryer was collected, resulting in Xbar=152.1 degrees. Assume that the distribution of melting point is normal with o=3.20. If the boiling point is different than 150 degrees, then either the oil will be too hot and will burn food or it will be too cool and will not properly cook the food. Is the sample mean significantly different from the target of 150 degrees? Use alpha=0.01 Но: H1: Define critical (rejection) region(s): Calculate the appropriate test statistic: What decision do we make? What this decision means in terms of this problem?
Dr. Caras was characterizing a cytochrome (an iron containing protein) from a new strain of bacteria. He obtained eight measurements of the percent iron in the protein: 0.3807%, 0.3803%, 0.3798%, 0.3793%, 0.3914%,0.3793%, 0.3803%, and 0.3796%. Calculate the mean (x) and standard deviation (s) for these results, %3= Use the Grubbs test to determine if one of these values is an outlier. What is the value of Gakculated?

What is the RPI index? How can the defective product rate of a production process be determined by using the RPI index? The average distribution range of 2 samples consisting of 4 units is R = 10.8 mm. The tolerance limit is plus – minus 10 mm. Calculate the RPI and evaluate if it will reject. What happens to the reject situation if the tolerance limit is plus-minus 20 mm?

A random sample of 75 eighth-grade students score's on a national mathematics assessment test has a score o 272. This test result prompts a state school administrator to declare that the mean score for the state’s eighth graders of this exam is more than 270. Assume that the population standard deviation is 30, At a = 0.03, is there enough evidence to support the administrator’s claim? Compare parts (a) through (e).
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 44 feet. Assume the population standard deviation is 4.9 feet. The mean braking distance for Make B is 46 feet. Assume the population standard deviation is 4.7 feet. At α=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).
