You may need to use the appropriate appendix table or technology to answer this question.The reliability of two types of machines used in the same manufacturing process is to be tested. The first machine failed to operate correctly in 111 out of 370 trials while the second typefailed to operate correctly in 64 out of 308 trials. (Let d = Machine 1 - Machine 2.)(a) Give a point estimate of the difference between the population proportions of these machines. (Round your answer to four decimal places.)(b) Calculate the pooled estimate of the population proportion. (Round your answer to four decimal places.)(c) Carry out a hypothesis test to check whether there is a statistically significant difference in the reliability for the two types of machines using a 0.10 level of significance.AO We do not reject Ho. There is no significant difference.O We do not reject Ho. There is a significant difference.Owe reject Ho. There is no significant difference.O We reject Ho. There is a significant difference.

Answer X1 =111x2 =64n1=370n2 =308level of significance =0.10This is a two-tailed test.

Solve all problems using a chi square analysis. You must use statistics to support your answers. 1. Azookeeper hypothesizes that changing the intensity of the light in the primate exhibits will reduce the amount of aggression between the baboons. In exhibit A, with a lower light intensity, he observes 36 incidences of aggression over a one-month period. In exhibit B, with normal lights, he observes 42 incidences of aggression. Should he support or reject his hypothesis? Observed Expected (o-e)/e (6-42)^2/e I X=? Degrees of freedom = 1 Critical value ?
A certain affects virus 0.4% of the population (in a population of 100,000 people, 400 will be infected with the virus). A test used to detect the virus in a person is positive 87% of the time if the person has the virus (true positive) and it is positive 14% of the time if the person does not have the virus (false positive). Fill in the remainder of the following table and use it to answer the questions below. Infected Not Infected Total Positive Test Negative Test Total 400 99,600 100,000

The temperature of a certain chemical process is thought to be related to the time it takes for the process to reach completion. Out goal is to that relationship so that we can use it to predict TIME TO REACH COMPLETION at various TEMPERATURES. 14 trials are set up and the time for the process to complete is measured for each of the different temperatures. The data is presented here:(data is in the image added to the question as well as more questions to answer)

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.In a combined study of northern pike, cutthroat trout, rainbow trout, and lake trout, it was found that 20out of 860fish died when caught and released using barbless hooks on flies or lures. All hooks were removed from the fish. (a) Let prepresent the proportion of all pike and trout that die (i.e., pis the mortality rate) when caught and released using barbless hooks. Find a point estimate for p. (Round your answer to four decimal places.)(b) Find a 99% confidence interval for p. (Round your answers to three decimal places.) lower limit upper limit
Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
