4. In a certain garden which has been treated with agro chemicals, new plants grow atan average rate of 10% within a square meter. When this same garden is not treatedwith agro chemicals, plants grow at an average rate of 30% within a square meter.You may assume that the number of plants that grow in the garden may be modelledby a Poisson distribution. Mr Amankwah Amaniapong has a rectangular gardenmeasuring seven-hundred centimeters by three hundred centimeters. He uses these same3|Pageagro chemicals to treat his garden. Mrs. Amankwah Amaniapong also has arectangular garden with a dimension of five hundred centimeters by four hundredcentimeters. She has decided not to apply these agro-chemicals in her garden.Find the probability that:a) Mr. Amankwah Amaniapong's garden has exactly 4 plants;b) Mrs. Amankwah Amaniapong's garden has at least 6 but fewer than 10 plants;c) Mr. Amankwah Amaniapong has at least one plant and Mrs. AmankwahAmaniapong's garden has none.

The 30 management professors at Omega University find out that telephone calls made to their offices are not being picked up. A call-forwarding system redirects calls to the management office after the fourth ring. A department office assistant answers the telephone and takes messages.An average of 90 telephone calls per hour is placed to the management faculty, and each telephone call consumes about one minute of the assistant’s time. The calls arrive to a Poisson distribution, as shown in Figure (a), with an average of 1.5 calls per minute. Because the professors spend much of their time in class and in conferences, there is only a 40 percent chance that they will pick up a call themselves, as shown in Figure (b). If two or more telephone calls are forwarded to the office during the same minute, only the first call will be answered.a. Without using simulation, make a preliminary guess of what proportion of the time the assistant will be on the telephone and what proportion of the…
In a Denver community, 50 cases of diabetes were reported among 15-19 years old out of a total population of 46,000 between September 1 to December 31, 2016. Ten percent (4,600) of the population were between 15-19 years old on April 1, 2016 and the size and age distribution of the population has remained constant. An investigation of the cases in the 15-19-year age group revealed that 22 of the reported cases were contracted prior to September 1. In addition, another 18 cases developed in April and May but were clinically resolved before September 1. What was the cumulative incidence rate of disease in 15-19 year olds per 1,000 population in this Denver community during the period September 1 to December 31, 2016?

1. Dick Hoover, owner of Modern Office Equipment, is concerned about freight costs and clerical costs incurred on small orders. In an effort to reduce expenditures in this area, he has decided to introduce a discount policy rewarding orders over $40 in the hope that this will cause customers to consolidate a number of small orders into large orders. The following data show the amount per transaction for a sample of 28 customers:10,15,20,25,15,17,41,50,5,9,12,14,35,18,19,17,28,29,11,11,43,54,7,8,16,13,37,18a. Compute the sample meanb. Compute the standard deviationc. Compute the sample varianced. If the policy is successful, will the mean of the distribution increase, decrease, or remain unaffected?e. If the policy is successful, will the standard deviation of the distribution increase, decrease, or remain unaffected?
Miller (2008) examined the energy drink consumption of college undergraduates and found that female useenergy drinks significantly less often than males. To further investigate this phenomenon, suppose that a researcher selects a random sample of n = 36 male undergraduates and a sample of n = 25 females. On average, the males reported consuming M = 2.45 drinks per month and females had an average of M = 1.28. Assume that the overall level of consumption for college undergraduates averages mean = 1.85 energy drinks per month, and that the distribution of monthly consumption scores is approximately normal with a standard deviation is = 1.2. Use alpha =.01
Suppose you manage the demand for a towing company in Little Rock which follows a poisson process. On a usual day your company gets 4 requests for towing services. What is the probability you will get 0 or 1 request a day? What is the mean, variance, and standard deviation for the numberof calls your company gets?
he Princeton Review, a company that tracks information about various colleges, reports that 30% of CofC students are out-of-state students. If we took many samples of CofC students, and for each sample calculate the proportion $\hat{p}$ of out-of-state students in that sample, what would be the center of this distribution?

An urban economist wishes to test the claim that the distribution of United States residents in the United States is different today than it was in 1999. In 1999, 19.6 % of the population of the United States resided in the Northeast; 23.0 % of the population of the United States resided in the Midwest; 35.4 % of the population of the United States resided in the South; 22.0 % of the population of the United States resided in the West. The economist randomly selects 2000 households in the United States and obtains the frequency distribution below. Region Frequency Northeast 365 Midwest 404 South 752 West 479 Test the claim that the distribution of residents in the United States is different today from the distribution in 1999 at alpha = .05
