A survey taken several years ago found that the average time a person spent reading the local daily newspaper was 10.8 minutes. The standard deviation of the population was 3 minutes. To see whether the average time had changed since the newspaper's format was revised, the newspaper editor surveyed 37 individuals. The average time that the 37 people spent reading the paper was 12.3 minutes. At =α0.01 , is there a change in the average time an individual spends reading the newspaper? Find the 99% confidence interval of the mean. Find the 99% confidence interval of the mean. Round the answers to nearest whole number. <<μ

Use a z-table such as https://www.math.arizona.edu/~rsims/ma464/standardnormaltable.pdf or an online calculator such as http://onlinestatbook.com/2/calculators/normal_dist.html to answer the following question: This question again refers to the study on blood pressure which has a normally-distributed set of blood pressures with a mean of 120.1 mmHg and a standard deviation of 15.1 mmHg. If you picked a member of the population at random, would it be more likely that you randomly select someone that: Has a blood pressure between 104 mmHg and 114 mmHg, or Has a blood pressure between 124 mmHg and 134 mmHg? Show any values calculated and explain your reasoning in the space provided below.
During the busy season, it is important for the shipping manager at ShipMundo to be able to estimate the time it takes the loading crew to load a truck. The shipping manager has found that she can model the load times using a normal distribution with a mean of 152 minutes and a standard deviation of 15 minutes. Use this table or the ALEKS calculator to find the percentage of load times between 116 minutes and 149 minutes according to the model. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).
An excess of high values for the cases distributed on a graph results in a positive skew in the data?
