Please show work in excel Katie likes to shop at VONS. For each trip to the retail store, Katie spends an average of 44 mins with a standard deviation of 10 mins. The length of time spent in the store is normally distributed. Find the probability distribution that the shopper will be in the store for more than 30 minutes. Find the probability distribution that the shopper will be in the store between 35 minutes and 40 minutes. If 300 shoppers enter the store how many shoppers would you expect to be in the store for each time interval listed above (a,b). Interpret the results from a-c.
Yoonie is a personnel manager in a large corporation. Each month she must review 10 of the employees. From past experience, she has found that the reviews take her approximately 4 hours each to do with a population standard deviation of 1.1 hours. Let X be the random variable representing the time it takes her to complete one review. Assume X is normally distributed. Let X¯¯¯ be the random variable representing the mean time to complete the 10 reviews. Assume that the 10 reviews represent a random set of reviews. (a) What is the mean, standard deviation, and sample size? Mean = Standard Deviation = Sample Size = (b) Complete the distributions. Round all decimals to four decimal places.

Ana is a dedicated Skee Ball player who always rolls for the 50-point slot. The probability distribution of Ana's score X on a randomly selected roll of the ball is shown here. The mean of this probability distribution is 23.8. Score Probability 10 0.32 20 30 40 0.27 0.19 0.15 50 0.07 What is the standard deviation of X? Interpret this value. σχ 12.632. The score of a randomly selected Skee Ball roll will typically vary from the mean (23.8) by about 12.632. = ox= 159.56. The score of a randomly selected Skee Ball roll will typically vary from the mean (23.8) by about 159.56. Oox = 159.56. The score of a randomly selected Skee Ball roll will vary from the mean (23.8) by 159.56. The standard deviation cannot be calculated in this situation because we do not have a list of randomly selected Skee ball point values. x = 12.632. The score of a randomly selected Skee Ball roll will vary from the mean (23.8) by 12.632.
Assume that the square footage of a residential house in the US is normally distributed with a mean=1000 and standard deviation=150 square feet. If we select a random house what is the probability that it will be at most 1050 square feet?
Assume that the average weight of an NFL player is 245.7 lbs with a standard deviation of 34.5 lbs. The distribution of NFL weights is not normal. Suppose you took a random sample of 32 players. What is the probability that the sample average will be greater than 234 lbs? Round your answer to three decimal places, How can I do this on excel? How do I include the greater than
The average student loan debt for college graduates is $25,750. Suppose that that distribution is normal and that the standard deviation is $10,350. Let X = the student loan debt of a randomly selected college graduate. Round all probabilities to 4 decimal places and all dollar answers to the nearest dollar. Find the probability that the college graduate has between $22,700 and $30,000 in student loan debt. (------) The middle 20% of college graduates' loan debt lies between what two numbers? Low: $(______) High: $(_____)
