a. Use the expected value approach to determine the optimal Alternative and its expected value. b. Compute the expected value with perfect information (i.e., expected value under certainty). c. Compute the expected value of perfect information (EVPI).

4 For estimating one proportion, when would you typically choose the bootstrap confidence interval over a classical (mathematical) confidence interval? O You don't have the required ten successes and ten failures. O You don't have a random sample. O You don't have a sample of size 30.

The data for this exercise was obtained from https://www.currentresults.com/Weather/Florida/yearly-florida-rainfall.php 2 . Tourists often hear about the wonderful, warm Florida weather; they live in blissful ignorance of the freezes experienced in the northern parts of the state. A tourism organization wants to open up the entire state to tourists. They know that not everyone is drawn to hot, sunny beaches, so they want to advertise the advantages of visiting other parts of the state. One of the first things they need to do is educate potential tourists about the weather. And part of that involves informing them about the average rainfall across the state. Your task is to help the tourism organization figure out what the average rainfall in Florida is like. Rainfall data is provided below. The table below gives the typical yearly rainfall in some parts of Florida. Place Rainfall (inches per year) Monticello 56.8 Niceville 71.0 Tampa 46.3 Lakeland 54.8 St. Augustine Lake City 49.0 52.6…

Let p equal the proportion of triathletes who suffered a training-related overuse injury during the past year. Out of 330 triathletes who responded to a survey, 167 indicated that they had suffered such an injury during the past year. a) Use these data to give a point estimate of p. 
 b)Use these data to find a 90% confidence interval for p. 
 c) Do you think that the 330 triathletes who responded to the survey may be considered a random sample from the population of triathletes?
