676 participants In the same study discussed in Question 3, the participants were also asked if they owneda car. The researchers found that 79% of the participants own a car. Suppose 83% of allCanadians own a car.a. Determine the parameter, estimator, and estimate.b. Can we determine the exact distribution of the estimator in this setting? If not, what isthe approximate distribution?c. Based on vour findings in part b, what is the probability that the estimate is greaterthan 75%?d. Based on your findings in part b, what is the probability that the estimate is between80% and 90%?e. What sample size would be needed if the researchers want the standard deviation ofthe estimator to be less than or equal to 0.01?

An agent for a property management company would like to be able to predict the monthly rental cost for apartments based on the size of the apartment as defined by square footage. A sample of the rent of 25 apartments in a college rental neighborhood was selected, and the information collected revealed the following: Apartment Size (Sq. Ft.) Monthly Rent ($) 1 850 950 2 1,450 1,600 3 1,085 1,200 4 1,232 1,500 5 718 950 6 1,485 1,700 7 1,136 1,650 8 726 935 9 700 875 10 956 1,150 11 1,100 1,400 12 1,285 1,650 13 1,985 2,300 14 1,369 1,800 15 1,175 1,400 16 1,225 1,450 17 1,245 1,100 18 1,259 1,700 19 1,150 1,200 20 896 1,150 21 1,361 1,600 22 1,040 1,650 23 755 1,200 24 1,000 800 25 1,200 1,750 e) Determine the coefficient of determination r2 and then completely interpret…

Question 4) The average height of a group is 165 cm and its standard deviation is 15 cm. Assuming that the lengths show normal distribution;a) Find the probability that a selected person is between 145 and 165 cm tall.b) Since the longest 35% will be transferred to another team, find out which neck will be added to another team.
For the frequency distribution, if you are to solve for the value corresponding to the 3rd Quartile, which among the classes will be the quantile class?
