- The average marks on an Economics Assignment is 55%, with a standard deviation of 5%. The Examiners note that the distribution of the marks is normal. A. Define 'Normal Distribution' including key properties and illustrate with a diagram. What is the proportion of frequencies below 35%? What is the proportion of frequencies above 80%? What is the proportion of marks between 40% and 70% ?Suppose that the distribution of Uber rides around the quoted arrival time is normally distributed. Themean waiting time (relative to the quoted time) is 0, with a standard deviation of 3 minutes.a. Using the empirical rule, what percentage of rides arrive within 3 minutes of the mean (3 minutesbefore to 3 minutes after)?b. Graphically depict the area that would need to be calculated to determine the probability ofwaiting more than 4 minutes for a ride. Explain your graph.aaaaaa A soft drink machine outputs a mean of 27 ounces per cup. The machine's output is normally distributed with a standard deviation of 3 ounces.

- Answer letter D only. Show complete solution. Thank you!Suppose you are shopping online for a new toy for your dog. As you look at the product reviews, you see the following distribution of ratings. Use this table for questions 2-5. Stars 5 4 3 st 2 IN 1 Frequency 9 3 2 1 5FIVE. Which of the following is true about standard deviation? The first step in calculating the standard deviation is calculating the square root. The second step in calculating the standard deviation is to subtract each measurement from the intermediate value and then square that difference. The last step in calculating the standard deviation is to sum the squared values and divide by the number of values minus one. Standard deviation is a type of average where the positive and negative numbers sum to zero. The amount of difference of the measurements from the central value is called the sample standard deviation.
- Please no written by hand solution Kate recently invested in real estate with the intention of selling the property one year from today. She has modeled the returns on that investment based on three economic scenarios. She believes that if the economy stays healthy, then her investment will generate a 30 percent return. However, if the economy softens, as predicted, the return will be 10 percent, while the return will be -25 percent if the economy slips into a recession. If the probabilities of the healthy, soft, and recessionary states are 0.6, 0.2, and 0.2, respectively, then what are the expected return and the standard deviation of the return on Kate❝s investment? Calculate the coefficient of variation for this investment. (Round expected return to 3 decimal places, e.g. 0.125 and round intermediate calculations and standard deviation to 5 decimal places, e.g. 0.07680.)Anticipated consumer demand in a restaurant for free-range steaks next month can be modeled by a normal random variable with mean 1,200 pounds and standard deviation 100 pounds. a.
