3. Suppose you are studying home prices, and you take a sample with a mean price of $300,000 and astandard deviation of $50,000. Suppose this data set is normally distributed.(a) Find the z-score of a home in this sample that sells for $420,000.(b) Find the z-score of a home in this sample that sells for $230,000.(c) What percentage of houses should sell at between $200,000 and $400,000?(d) According to Chebyshev's Rule, what is the minimum percentage of houses that should sell atbetween $150,000 and $450,000?

Given that. X~N( μ , ?) μ=300000 , ?=50000 Z-score =( x - μ )/? NOTE:- According to…

Answered: standard deviation of $50,000. Suppose…

One of the z-score formulas will help on this question. Scores on the SAT test are normally distributed with a mean of 500 and standard deviation of 100 points. Pretend someone scored 400 on the math portion of the SAT test. What would be the z-score cut off for this score? A. 1.0 B. -1.0 C. 0 D. 2.0
Karl Pearson developed a measure that describes the skewness of a distribution, called the coefficient of skewness. The formula is Skewness = 3 (mean-median)/standard deviation. The value of this measure generally lies between -3 and +3. The closer the value lies to -3, the more the distribution is skewed left. The closer the value lies to +3, the more the distribution is skewed right. A value close to 0 indicates a symmetric distribution. Find the coefficient of skewness of the following distributions and comment on the skewness. Compute the coefficient of skewness for the data in Problem 25 Problem 25 data: The following data (see photo) represent the weights (in grams) of random sample of 50 M&M plain candies.

Your Turn: Standardized Scores Scores on the final exam in Ms. Meyer's statistics class follow a normal distribution, with a mean of 82 and a standard deviation of 5. 1. Ron, who took Ms Meyer's class, scored 88 on the final. Ron's z-score is Click to view hint 2. This means that Ron's final score is Click to view hint 3. Dan also took Ms. Meyer's class, and the z-score of his final is -2.4. This means that Dan's score is: Click to view hint 4. Dan's actual score on the final is Click to view hint 5.
