A model for lifetimes, with a bathtub-shaped hazard rate, is the ex-ponential power distribution with survivai function S(x) = exp{1exp((A.x)"]}.–(a) If a = 0.5, show that the hazard rate has a bathtub shape and findthe time at which the hazard rate changes from decreasing to increasing.(b) If a = 2, show that the hazard rate of x is monotone increasing.

According to recent data the survival function for life after 63 is approximately given by S(x) = 1-0.052x-0.078x² where x is measured in decades. This function gives the probability that an individual who reaches the age of 63 will live at least x decades (10x years), longer. a. Find the median length of life for people who reach 63, that is, the age for which the survival rate is 0.50. ye years (Round to the nearest whole number as needed.)

In Example 6 we used data from 1920 and projected to 2050 and found that the expected life span in the United States can be modeled as a function of the year of birth by L(x) = 8.7744 + 14.907 ln(x) where x is the number of years after 1900. Using data from 1920 to 1989, the model ℓ(x) = 11.616 + 14.144 ln(x) where x is the number of years after 1900, predicts expected life span as a function of birth year. Use both models to predict the life spans for people born in 2006 and in 2022. (Round your answers to two decimal places.) model L: 2006 years model L: 2022 years model ℓ: 2006 years model ℓ: 2022 years Did adding data from 1990 to 2050 give predictions that were quite different from or very similar to predictions based on the model without that data? The additional data gave predictions that were quite different than (i.e., more than 5 years removed from) predictions based on the earlier model. The additional data gave predictions that were very…
