- NarStor, a computer disk drive manufacturer, claims that the average time to failure for its hard drives is 14,400 hours. You work for a consumer group that has decided to examine this claim. Technicians ran 16 drives continuously for three years. Recently the last drive failed. The time to failure (in hours) are given below.

Use alpha = 0.01 What assumption did you make in performing the test? What is the p-value?A school board has a plan to increase participation in the PTA. Currently only about 27 parents attend meetings. Suppose the school board plan results in logistic growth of attendance. The school board believes their plan can eventually lead to an attendance level of 81 parents. In the absence of limiting factors, the school board believes its plan can increase participation by 10% each month. Let m denote the number of months since the participation plan was put in place, and let P be the number of parents attending PTA meetings. (a) What is the carrying capacity K for a logistic model of P versus m? K = (b) Find the constant b for a logistic model. b = (c) Find ther value for a logistic model. Round your answer to three decimal places. r = (d) Find a logistic model for P versus m. P =4. Let 0 ‡ b, c E Rn and define A = be E Rnxn. Show that (a) R(A) = span{b}, (b) N(A) = {x ≤ R" | c²x = 0}.
- Alaska's Katmai National Park celebrates fat bear week every year in the beginning of October, when brown bears are getting ready to go into hibernation. During the fat bear week, the public votes on bears to advance in the bracket through single-elimination rounds. Adult male bears regularly weigh around and even over 1000 pounds for their peak fall weights, while adult female bears generally weigh 1/3 less than the males. Suppose the weights of all ready-to-hibernate brown bears in the national park are distributed as shown in the following histogram. Weights of Bears 10 200 400 600 800 1000 1200 Weight in pounds The mean of all the peak fall bear weights is 695 pounds, and the standard deviation is 279 pounds, For a random sample of 30 bears, what is the probability of obtaining a sample mean less than 720 pounds? If the conditions to perform the necessary calculation are not satisfied, enter -1" instead. Give your answer accurate to four digits beyond the decimal point. Answer.…lecture(12.11A): Researchers were interested in the effects of co-sleeping on nightime waking and crying in infants. .They assesed the number of minutes parents reported that their infants were awake and crying for a period of three days. Five of the infants co-slept with thier mothers(Co) and four infants slept in crib(Cr).The researchers wanted to see if there was a difference in the total number of minutes of crying during the 3 nights. for the two groups. A summary of the data is given below Co-sleepers night time crying in minutes: 8, 4, 7, 7, 6 Crib-sleepers night time crying in minutes: 30, 17, 22, 25 Test the hypotheses at (aplha=.05) level of signifcance. using the 5 step hypotheses testing procedure. Clealy state the null and alternative hypotheses. Round your answer to 2 decimal places.A research study in a big metropolitan area shows that 2% of individuals living within the city limits move to suburbs during one-year period while 1% of individuals living in the suburbs move to the city during a one-year period. 1.

The participants (n=30) ran a 100 meter sprint before the consumption of caffeine on day 1 and then they ran another 100 meter sprint on the following day 2 after ingesting caffeine. The average time taken to run the 100 meter sprint on day 1 was (M1) and the average to run on day 2 after caffeine was (M2). The variance for this study was calculated to be (S2). Does caffeine use improve the running time in the 100 meter sprint (e.g., lower time)? Use all of the data provided to you below and test at an alpha of 0.05.
