I need typing clear urjent no chatgpt used i will give 5 upvotes pls full explain Question 5A study was conducted to compare the pollution levels of two lakes (Lake A and Lake B).The pollution levels are compared by using the dissolved oxygen levels in the water. Lowerdissolved oxygen levels are indicative of higher pollution levels. Seven water specimensfrom Lake A and six water specimens from Lake B are randomly and independently selected,and the dissolved oxygen levels (measured in mg/L) of the water specimens are recorded asfollows.Lake ALake B7.26.87.16.37.56.56.96.35.76.56.15.85.32Assume that the dissolved oxygen levels of water from both lakes are normally distributed.(a) At the 0.01 level of significance, is there sufficient evidence to conclude that Lake B ismore polluted than Lake A?(b) At the 0.05 level of significance, do the data provide sufficient evidence to concludethat the population standard deviation of the dissolved oxygen level of water in Lake Bis different from 0.4?(c) At the 0.05 level of significance, do the data provide sufficient evidence to concludethat the population standard deviation of the dissolved oxygen level of water in Lake Bis higher than that in Lake A?

On February 12 Peg Jones, vice president for operations and maintenance, called into Stephen’s office and asked to study the issue. Specially, Stephen wanted to know whether the average fleet age was correlated to direct airframe maintenance costs, and whether there was a relationship between average fleet age and direct engine maintenance costs. Peg was to report back by February 26 with the answer, along with quantitative and graphical descriptions of the relationship. Peg’s first step was to have her staff construct the average age of Northern and Southeast B727-300 fleets, by quarter, since the introduction of that aircraft to service by each airline in late 1993 and 1994. The average age of each fleet was calculated by first multiplying the total number of calendar days each aircraft had been in service at the pertinent point in time by the average daily utilization of the respective fleet to total fleet hours flown. The total fleet hours was then dividend by the number of…
