The length of unemployment for individuals during a pandemic has mean of 32 weeks and standard deviation is 2.6 weeks. Assume that the length of unemployment has a Normal distribution. You select a random sample of 324 unemployed individuals and record how long they have been unemployed. Find the probability that the length of unemployment of a single randomly selected individual is greater than 31.9. 324 is greater Find the probability that the average length of unemployment for the sample...

A population of values has a normal distribution with μ=176.9 and σ=81. You intend to draw a random sample of size n=181. Find the probability that a sample of size n=181 is randomly selected with a mean between 178.1 and 178.7. P(178.1 < M < 178.7) = Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted. A leading magazine (like Barron's) reported at one time...

A leading magazine (like Barron's) reported at one time that the average number of weeks an individual is unemployed is 38 weeks. Assume that for the population of all unemployed individuals the population mean length of unemployment is 38 weeks and that the population standard deviation is 6 weeks. Suppose you would like to select a random sample of 35 unemployed individuals for a follow-up study Find the probability that a single randomly selected value...

A Food Marketing Institute found that 46% of households spend more than $125 a week on groceries. Assume the population proportion is 0.46 and a simple random sample of 76 households is selected from the population. What is the probability that the sample proportion of households spending more than S125 a week is more than than 0.38 Note: You should carefully round any z-values you calculate to 4 decimal places to match wamap's approach and calculations Answer 1,00000 (Enter your...
