Giselle has purchased the insurance policy from an insurance company to cover the value of hers new car in case if it gets totaled for the price of $1300 per year. Giselle's car worth $21000 and the probability of her totaling the car during the length of the policy is estimated to be 0.3%. Let XX be the insurance company's profit. Answer the following questions: 1. Create the probability distribution table for XX :  XX  outcome profit xx ,$  P(X=x)P(X=x)    car is totaled       car is not totaled     2. Use the probability distribution table to find the following:  E[X]=μX=E[X]=μX= dollars. (Round the answer to 1 decimal place.)  SD[X]=σX=SD[X]=σX= dollars. (Round the answer to 1 decimal place.)

For each probability and percentile problem, draw the picture.The speed of cars passing through the intersection of Blossom Hill Road and the Almaden Expressway varies from 15 to 35 mph and is uniformly distributed. None of the cars travel over 35 mph through the intersection. Find the probability that the speed is more than 29 mph given (or knowing that) it is at least 20 mph. (Enter your answer as a fraction.)

According to Reader's Digest, 50% of primary care doctors think their patients receive unnecessary medical care. Use the z-table. a. Suppose a sample of 390 primary care doctors was taken. Show the sampling distribution of the proportion of the doctors who think their patients receive unnecessary medical care. E(p)= (to 2 decimals) (to 4 decimals) b. What is the probability that the sample proportion will be within +0.03 of the population proportion? Round your answer to four decimals. c. What is the probability that the sample proportion will be within 10.05 of the population proportion? Round your answer to four decimals. d. What would be the effect of taking a larger sample on the probabilities in parts (b) and (c)? Why? The probabilities would -Select your answer - This is because the increase in the sample size makes the standard error, ,- Select your answer - ✪

For the fiscal year​ 2007, a tax authority audited 1.74​% of individual tax returns with income of​ $100,000 or more. Suppose this percentage stays the same for the current tax year. What is the probability that two randomly selected returns with income of​ $100,000 or more will be​ audited?

Please answer items 4, 5, 6 and 7. Please provide the correct answer. Thank you.

Vanessa is interested in purchasing the local coffee shop in a small town in Central California. After examining accounting records for the past several years, she found that the coffee shop has been grossing over $850 per day about 62% of the business days it is open. Estimate the probability that the store will gross over $850 for the following. (Round your answers to three decimal places.)a.) at least 3 out of 5 business days b.) at least 6 out of 10 business days c.) fewer than 5 out of 10 business days d.) fewer than 6 out of the next 20 business days If the outcome described in part (d) actually occurred, might it shake your confidence in the statement p = 0.62? Might it make you suspect that p is less than 0.62? Explain. Yes. This is likely to happen if the true value of p is 0.62. Yes. This is unlikely to happen if the true value of p is 0.62. No. This is likely to happen if the true value of p is 0.62. No. This is unlikely to happen if the true value of p is 0.62. e.) more…

Sarah throws a fair die multiple times, recording the total number of "2"s she throws and then calculating the proportion of "2"s she has thrown so far after each throw. She then constructs a graph to visualize her results. Which of the following statements is FALSE? a. This is an example of the law of large numbers. b. The theoretical probability of getting a 2 is 0.167 for each throw. c. The relative frequency of "2"s thrown changes as Sarah throws the die more. d. The probability distribution for the possible number of outcomes changes as the total number of throws increases.

The following data come from a study of the relationship between health risk and income. The number of low income people is 2680, the number of medium income people is 2550, and the number of high income people is 1700. Type the probability that someone in this study is from the low income group or from the medium income group. (Type the probability rounded to two decimal places with no 0; e.g., .34). solve it step by step please

If a 60 year-old buys a $1000 life insurance policy at a cost of $70 and has a probability of 0.921 of living to age 61, find the expectation of the policy until the person reaches 61. Round your answer to the nearest cent

Aiyana has purchased the life insurance policy for her snake for the price of $100 per year and Aiyana will receive $5000 in case if her snake passes away. The insurance company estimated the probability of her snake passing away during the length of the policy to be 0.2%. Let XX  be the insurance company's profit. Answer the following questions: 1. Create the probability distribution table for XX :  XX  outcome profit xx ,$  P(X=x)P(X=x)    snake passes away       snake survives     2. Use the probability distribution table to find the following:  E[X]=μX=E[X]=μX= dollars. (Round the answer to 1 decimal place.)  SD[X]=σX=SD[X]=σX= dollars. (Round the answer to 1 decimal place.)
