- Suppose the reaction times of teenage drivers are normally distributed with a mean of 0.53 seconds and a standard deviation of 0.11 seconds. A. What is the probability that a teenage driver chosen at random will have a reaction time less than 0.65 seconds?Suppose the reaction times of teenage drivers are normally distributed with a mean of 0.53 seconds and a standard deviation of 0.11 seconds. a)What is the probability that a teenage driver chosen at random will have a reaction time greater than 0.8 seconds?suppose diastolic blood pressure in hypertensive women centers about a mean of 100 mm Hg with a standard deviation of 14 mm Hg and is normally distributed. If four such woman are randomly selected, find the probabilty that their mean diastolic pressure is greater than 115.
- The production manager of a packaging company claims that the difference between the mean lengths of all corrugated boxes produced by two separate machines (M1 and M2) is at least 10.37 millimeters. A random sample of 181 corrugated boxes taken from Machine 1 (M1) produced a mean length of 177.40 millimeters, while a random sample of 99 corrugated boxes selected from Machine 2 (M2) gave an average length of 165.83 millimeters. The standard deviations for both populations are 3.02 millimeters and 5.61 millimeters, respectively. Assuming that both distributions are approximately normally distributed, test the hypothesis at 5% significance level and indicate if there is sufficient evidence to reject the production manager’s claim. Use the 24 critical-value approach.Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 18 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.11 oz, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost all cans have volumes between 11.95oz and 12.59oz, the range rule of thumb can be used to estimate that the standard deviation should be less than 0.16 oz. Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.16oz. Use a 0.05 significance level. 1. Compute the test statistic X2 = 2. Identify the p-valueThe manager of a computer retails store is concerned that his suppliers have been giving him laptop computers with lower than average quality. His research shows that replacement times for the model laptop of concern are normally distributed with a mean of 3.2 years and a standard deviation of 0.5 years. He then randomly selects records on 35 laptops sold in the past and finds that the mean replacement time is 3 years.Assuming that the laptop replacment times have a mean of 3.2 years and a standard deviation of 0.5 years, find the probability that 35 randomly selected laptops will have a mean replacment time of 3 years or less.P(x-bar < 3 years) = Enter your answer as a number accurate to 4 decimal places.

- Workers at a certain soda drink factory collected data on the volumes (in ounces) of a simple random sample of 21 cans of the soda drink. Those volumes have a mean of 12.19 oz and a standard deviation of 0.11 oz, and they appear to be from a normally distributed population. If the workers want the filling process to work so that almost all cans have volumes between 11.94 oz and 12.54 oz, the range rule of thumb can be used to estimate that the standard deviation should be less than 0.15 oz. Use the sample data to test the claim that the population of volumes has a standard deviation less than 0.15 oz.
