- Find the anitderrivativeA logging company wants to calculate the total amount of volume in cubic meters of wood, in logs that can be extracted from a eucalyptus forest. The perimeter of the log is easy to obtain, but the height is difficult to measure. Not even with the use of an appropriate instrument is it possible to measure because the trees are too close to each other. The forestry engineer in charge decides to try a sampling estimate. The idea is to measure the trunk perimeter and height (until the beginning of the branch) of 13 randomly selected trees and extend the result obtained to all 2000 trees in the forest. It is known that there is a constant relationship between the height (Y) and the perimeter of the trunk (X) of the tree. Thus, the engineer proposes that 13 trees with trunks of different perimeters be selected and their heights measured. Next, he proposes to fit a linear regression model to the data obtained yi = a + bxi + ei. The model will provide a value that establishes the relationship…As an analyst, we would like to perform a work sampling study on an assembly line. The jobs can bedifferentiated on the basis of the product size: A, B, and C. We perform a study over a five-week periodthat equals to 200 working hours. There are 12 workers to be examined. In total, we perform 1140observations. Yet, the worker absences lead to 15 worker-day deduction from the total working hourswhere workers work 8 hour each day. The study results are tabulated below.

In the table below, the amount of products transported by both ways and the transportationThe number of broken ones is given. Accordingly, which transportation route should be preferred at the 5% significance level?A consumer testing agency wants to evaluate the claim made by a manufacturer of discount tires. The manufacturer claims that its tires can be driven at least 35,000 miles before wearing out. To determine the average number of miles that can be obtained from the manufacturer’s tires, the agency randomly selects 60 tires from the manufacturer’s warehouse and places the tires on 15 cars driven by test drivers on a 2-mile oval track. The number of miles driven (in thousands of miles) until the tires are determined to be worn out is given in the following table. Car 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 n y s Miles Driven 25 27 35 42 28 37 40 31 29 33 30 26 31 28 30 15 31.47 5.04 a. Place a 99% confidence interval on the average number of miles driven, m, prior to the tires wearing out. b. Is there significant evidence (a 5 .01) that the manufacturer’s claim is false?

Carryout an appropriate hypothesis test (use 1% significance level). Check any assumptions you think are relevant before doing the text.A company's quality engineer wants to check whether the average weight of the products coming out of the packaging line does not exceed 10 grams. For this, he measured the weights of the products coming out of the line by making random selection. Measurement values respectively; 8, 11,9,11,9,7,11,10,10,9. After a while ; A press machine with a newer technology has been replaced by a press machine where product losses are frequently experienced in the packaging line. and products with the same features were weighed after being processed in this new pressing machine. After the new pressing machine, the weights of the products were measured as follows; 8,8,13,17,8,12,16,14,13,15. a) Test whether the average weight of the products currently exceeds 10 grams or not, at a = 0.05 significance level, by writing the relevant hypotheses and applying all necessary steps to make a decision. Write down the decision you made as a result of the hypothesis test and interpret your decision. b)The…The state education commission wants to estimate the fraction of tenth grade students that have reading skills at or below the eighth grade level. Step 1 of 2: Suppose a sample of 333 tenth graders is drawn. Of the students sampled, 260 read above the eighth grade level. Using the data, estimate the proportion of tenth graders reading at or below the eighth grade level. Enter your answer as a fraction or a decimal number rounded to three decimal places. Step 2 of 2: Suppose a sample of 333 tenth graders is drawn. Of the students sampled, 260 read above the eighth grade level. Using the data, construct the 80% confidence interval for the population proportion of tenth graders reading at or below the eighth grade level. Round your answers to three decimal places.

This was more days of rain themany of the other weather station reported that year, but it was not considered unusualfor San Juan. By comparison, the situation at Phoenix Arizona, reported 31 days ofprecipitation during the same year (again, not unusual).i. Suppose you were taking a one-day business trip to San Juan.
