Question:
I decided to compare the type of households in my town, which is Northbrook, IL. The variable that I chose to focus on was occupied housing units, and I compared the data from 2015 to the data from 2019. In 2015, the number of occupied housing units was estimated at 4,794,523 versus 4,866,006 in 2019. As you can see, there is a difference, because the variable measurement was higher in 2019 (US Census Bureau, n.d.).?
?
If I wanted to test these differences statistically, I would use a null hypothesis. My null hypothesis would be: there is no change in the number of occupied housing units in Northbrook, IL. ?
?
H0 : = 4,794,523?
?
Ha : > 4,794,523?
?
This difference does not seem to be significant with a 1.4% increase from 2015 to 2019 in the occupied housing units in Northbrook, IL. This difference is important to show that there has been very little change in housing occupancy. One of the consequences of this change in my community would be a small increase in property value, as more people occupy the units in Northbrook. However, a significant decrease in housing occupancy in a town would significantly lower property values, thus attracting less buyers to the area.?

Find the probability that an individual distance is greater than 218.40 cm. b. Find the probability that the mean for 20 randomly selected distances is greater than 203.50 cm. c. Why can the normal distribution be used in part (b). even though the sample size does not exceed 30? a. The probability is 0.6255 (Round to four decimal places as needed.)roblem 4: (15 Points) 1. (10 points) From past experience, it is known that the number of tickets pur- chased by a customer standing in line at the ticket window for the BTS (Bangtan Boys: A South Korean Band) concert follows a distribution that has mean u = 2.5 and standard deviation o = 2.0. Suppose that few hours before the start of one of these concerts at DFW, there are 99 eager students from ENGR 3341 and their professor standing in line to purchase tickets. If only 240 tickets remain, use the cental limit theorem (CLT) and Q-table to find the probability that all 99 students and the professor (i.e. a total of 99 + 1 = 100 people) will be able to watch the concert together. 2. (5 points) Using Chebyshev inequality, calculate the percentage of observations (i.e. outcomes) that would fall outside 2 standard deviations of the mean. nswer to Problem 4:e) Suppose X; are iid exponential parameter A r.v.s and that Y, = X2. Verify that the Cental Limit Theorem (CLT) applies to the r.v.s Y,. Then find the limit distribution of n( Yn - a) b where a, b are the mean and standard deviation of Y,. Also find the values of a, b in terms of the parameter A.mad & & Putshis OpenStem - Google Dri.

Their coach wants to identify the team members in the bottom 33%% for extra tutoring help. What is the grade point average that will mean that a track team athlete will be recommended for extra tutoring help if the coach examines just 32 of her athletes?
