A fitness company is building a 20-story high-rise. Architects building the high-rise know that women working for the company have weights that are normally distributed with a mean of 143 lb and a standard deviation of 29 lb, and men working for the company have weights that are normally distributed with a mean of 165 lb and a standard deviation or 29 lb. You need to design an elevator that will safely carry 15 people. Assuming a worst case scenario of 15 male passengers, find the maximum total allowable weight if we want a 0.99 probability that this maximum will not be exceeded when 15 males are randomly selected. maximum weight =      -lb Round to the nearest pound.

We conduct a test of hypothesis of Ho : p = 0.3 vs. HA : p > 0.3. The value of the test statistic is -2.00. Which picture represents the appropriate p-value? A -2 C Select one: a. A b. B С. C d. D O O O O

Q2. Define population in terms of statistics and describe why are samples needed and how are they collected. Give an example of a population and sample.

A California lake has been stocked with rainbow trout. These trout have an average length of 24 inches, with a standard deviation of 3 inches. Someone goes fishing and catches a trout that is 26.25 inches long. Express the length of this trout in standard units, relative to all the trout that were used to stock the lake. Choose the answer below that is closest.

You will be comparing two sets of data for this assignment. 1. Determine the average number of toilet paper rolls* for Fall 2022 biochemistry and genetics students (individually) and calculate the standard deviation of each using the equation. Please be sure to show your work. I know that you can easily use tools like Microsoft Excel to calculate standard deviation, but I would like to see you complete the work by hand so that you get a sense of the role of each component of the equation. Ignore students that did not provide answers (don't use those students in the mean or N value calculations). 2. Please answer the following questions when you submit your data. Which group had a higher mean number of rolls of toilet paper? Which value had the most variability? Referring to the equation, how could you decrease the amount of variability in the mean? Did you find the variation surprising or unexpected?  The two sets of data and the standard deviation formula pictures are attached…

If we collected data on how many pets each person in our class has, describe a situation that the standard deviation would be 0. Jo thinks that the only way for this to happen is for everyone to have no pets. Explain to Jo why the answer they have is correct, but not the only way.

The total cost for a production process is $600 minus two times the number of units produced. The mean and variance of the number of produced are 200 and 20, respectivelySo, the mean and variance of the total cost are A.560,1000 B.80,200 C.180,400 D. 200,600

Please provide a clear and complete solution. Answer quickly for I have 30 minutes left. Thank you.

After calculating the mean and standard deviation, how do we interpret the result, and when a variable look strange?

A normally distributed data set has a mean of 0 and the standard divitation of 2. What is the percent of valleys between -4.0 and 2.0?
