The quality control manager of a tire company wishes to estimate the tensile strength of a standard size of rubber used to make a class of radial tires. A random sample of 61 pieces of rubber from different production batches is subjected to a stress test. The test measures the force (in pounds) needed to break the rubber. According to the sample results, the average pressure is 238.4 pounds with a population standard deviation of 35 pounds. Determine the 98 percent confidence interval.

The Confidence Interval is (227.96 , 248.84)

Step-by-step explanation:

The sample size is given as n = 61

The average pressure is given as = 238.4 pounds

The standard deviation is given to be = 35 pounds

The data collected for the radial tires is considered to be normally distributed.

Since the population is normally distributed the sample is also normally distributed, therefore = =238.4 pounds

The confidence interval is given as C.I. = 98% = 0.98

Therefore the Significance Level, = 1 - 0.98 = 0.02

Critical Z value is given as =

The Confidence Interval is given by the formula CI  =

                                 Therefore C.I.  =

                                                          = 238.4 ± 10.441

                                                          = 227.96 , 248.84

you forgot the options, but i found them anyways, the correct answer is "john wilson believes that words and actions based on the intellect are superior to those based on emotions".

john wilson is depicted as an extremely intelligent man. the point of the excerpt is to make a sort of distinction between emotional and rational intelligence. he happens to have both attributes, but he clearly favors his intellectual gifts. at the same time, because of his religious background, he's a little bit conflicted with this and it makes him ashamed.

hope this !
