Engineers observe that about 90% of graphite samples fracture within 5 hours when subjected to a certain stress. (a) If the time to fracture is modeled with an exponential distribution, what would be a suitable value for the parameter λ? (b) Use the model to estimate the probability that a fracture occurs within 3 hours.

A technology specialist studied the relationship between time spent on social media and age. One observation found that a 50-year-old person spends 2 hour per week on social media. A second observation showed that a 25-year-old person spends 12 hours per week on social media. Assuming time spent per week on social media 7 (in hr) is a linear function of age a (in yr), find a linear model of this event. TH x Use the model to find the age (in yr) of a person who spends 10 hours per week on social media. 30 уг
An individual has been exercising at a local gym for about 10 years. He always begins with a 10- to 15-minute session on the treadmill at a speed of 3.7 mph. During a 12-day period in 2010, he recorded his heart rate before using the treadmill and after 5 minutes of use. The data are shown in Table 8.37 (image attached). The subject also recorded his heart rate at baseline and 5 minutes after starting the treadmill exercise (at a speed of 2.5 mph) in 2000. The data are shown in Table 8.38 (image attached). Implement a test to compare the baseline heart rate initially (2000) and after 10 years of experience (2010), and report a two-sided p value.
Suppose the probability x(z) of reaching a target (such as getting a ball between goal posts) as a function of distance x (in metres) from the target is well-fitted by a logistic regression equation with log(r(z)/1 - (z)) = 6.4 - 0.13z Please answer below to 3 significant digits. Part a) For this prediction model, what is the probability of reaching the target from a distance of 35 metres. Part b) At what distance is the probability of reaching the target equal to 0.6?

One of the factors that determines the degree of risk a pesticide poses to human health is the rate at which the pesticide is absorbed into skin after contact. An important question is whether the amount in the skin continues to increase with the length of the contact, or whether it increases for only a short time before leveling off. To investigate this, measured amounts of a certain pesticide were applied to 20 samples of rat skin. Four skins were analyzed at each of the time intervals 1 , 2 , 4 , 10 , and 24 hours. The amounts of the chemical (in micrograms) that were in the skin are given in the following table. Duration Amounts Absorbed 1 1.3 1.4 1.3 2.1 2 1.6 2.0 1.3 2.0 4 1.9 1.6 2.1 1.7 10 2.0 2.1 2.0 1.7 24 2.4 2.2 2.6 2.2 Can you conclude that the amount in the skin varies with time?

The following data are annual 15-min peak rainfall intensities I (in./hr) for 9 years of record. Compute and plot the log,,-normal frequency curve and the data. Use the Weibull plotting position formula. Using both the curve and the mathematical equation estimate (a) the 25-yr, 15-min peak rainfall intensity; (b) the return period for an intensity of 7 in./hr; (c) the probability that the annual maximum 15-min rainfall intensity will be between 4 and 6 in./hr.
