A university IT centre has upgraded its hardware in their servers used by students submitting their work to the LMS during times of peak congestion. Some statistics were collected in order to evaluate the performance of the new hardware. Before the upgrade was made, a trial submission was made on a random selection of 32 servers in the cluster during a busy time. The mean delay between clicking "Submit" and the submission being uploaded and saved was 5.3 seconds, with standard deviation 0.9 seconds. Following the upgrade, the same trial submission was made on the same 32 servers, yielding a mean delay of 4.9 seconds with standard deviation of 0.8 seconds. The mean of the differences of these delay times was -0.40 seconds with standard deviation of 0.32 seconds. 1. Carry out a hypothesis test to evaluate whether the hardware upgrade made any difference to delay times for submissions. Use the 5% level of significance and a p value decision rule.

On average, a flight reservation center can handle 190 customer calls per day with a standard deviation of 25 calls. Use the empirical rule to estimate the minimum and maximum number of calls that the flight reservation center can handle in a day.
The time to complete the Advanced Placement (AP) Statistics Exam in previous years is normally distributed with an average time of 2.4 hours. Because of school closures due to COVID-19, the College Board offered an at-home test for the 2020 AP Statistics Exam. A teacher feels that students, on average, will have a different completion time for the at-home exam. They take a random sample of 25 students that took the exam and their mean time was 2.74 hours with a standard deviation of 0.25 hours. Test to see if the mean time has significantly changed using a 5% level of significance. Give answers to at least 4 decimal places. What are the correct hypotheses? Ho: M H₁: P Based on the hypotheses, find the following: Test Statistic t = Critical-Value t = ± 2.4 #v 2.4 o hours hours
A SimAirlines aircraft that flies between BWI and San Diego airport has 100 seats, and there are two types of fares: full ($500) and discount ($300). Although there is an unlimited demand for the discount fare, demand for the full fare is estimated to be normally distributed with mean 24 seats and standard deviation 16 seats. To maximize the revenue generated from this flight, how many seats SimAirlines should protect for full-fare passengers?
A manufacturer of office machines is considering the production of a new word processor. The decision to start large-scale production of the new machines will be based on the comparison of the mean operating speed using the standard machines (µx) and the mean operating speed using the new machines (µy). Since operators of the machine have varying abilities, a random sample of 20 typists was selected and the speed of each typist in the sample was observed once using the new word processor and once using the standard word processor. The collected data on the speed (in minutes) are as follows: Typist (i) Standard Processor (Xi) 1 2 3 4 5 6. 8 10 60.2 58.7 59.4 60.3 61.7 60.2 64.1 63.2 62.4 57.8 New Processor (Yi) 57.2 57.4 56.4 58.5 60.1 61.4 61.9 60.4 60 56.8 Typist (i) Standard Processor (Xi) 11 12 13 14 15 16 17 18 19 20 55.4 61.2 64.7 64.1 62.9 65.8 69.3 56.4 58.5 63.7 New Processor (Yi) 50.2 58.4 63.5 60.5 62.2 66.3 68.5 56.6 58.3 60.2 Assuming normality, compute a 95% confidence…
A researcher is studying hospitals cleanliness comparing carpeted rooms with uncarpted rooms. This researcher would like to determine if the mean number of airborne bacteria (per cubic foot) in carpeted rooms differs from the mean amount of airborne bacteria in uncarpeted rooms. To test thus, carpeted and uncarpeted hospitals rooms were randomely selected. Then air from the room was pumped over a petri dish and the number of bacteria of the patri dish was recorded. Since both samples are small (less than 30), you may assume that number of bacteria per petri dish is normally distributed. Using significant level =.05, use the unequal varance t-test for means to determine if the mean number of airborne bacteria in carpeted rooms differs from the mean number of airborne bacteria in uncarpeted rooms. Follow all steps and remember that you must assign population 1 and population 2 before you set up your Ho and Ha.
As part of a staged rollout, a new email client was installed on some of the computers of a major company's customer service representatives (CSRS). One of the company's performance analysts has been tasked with estimating the difference on the busiest day of the year between the mean time (in minutes) spent working on email for CSRS using the new email client and the mean time (in minutes) spent working on email for CSRS using the old email client. On the busiest day of the year, the performance analyst studies a random sample of 16 CSRS using the new email client and a random sample of 18 CSRS using the old email client. (These samples are chosen independently.) The analyst records the amount of time (in minutes) each CSR spends working on email. These data are shown in the table. Times working on email (in minutes) New email client 166, 188, 207, 172, 202, 148, 192, 173, 197, 197, 158, 172, 209, 185, 203, 169 Old email client 78, 196, 145, 195, 109, 85, 95, 138, 232, 47, 146, 122,…
The time to complete the Advanced Placement (AP) Statistics Exam in previous years is normally distributed with an average time of 2.6 hours. Because of school closures due to COVID-19, the College Board offered an at-home test for the 2020 AP Statistics Exam.

Are juvenile defendants who are released pending adjudication processed more slowly than those who are detained? The JDCC data set records whether a juvenile was released and the number of months it took for that juvenile’s case to reach a disposition. The sample will be narrowed to black female youth. Released juveniles (Sample 1) had a mean of 4.30 months to disposition (s = 3.86, N = 123) and detained juveniles (Sample 2) had a mean of 3.57 (s = 4.20, N = 64). Using an alpha level of .01, test the hypothesis that released juveniles’ mean time-to-adjudication is significantly greater than detained juveniles’ mean. Assume equal population variances. Use all five steps.
A personnel director wishes to compare the effectiveness of two methods of train- ing industrial employees to perform a certain assembly operation. Employees are to be divided into two equal groups: the first receiving training method 1 and the sec- ond training method 2. Each will perform the assembly operation, and the length of assembly time will be recorded. It is expected that the assembly times for both groups will have a range of approximately 8 minutes. For the estimate of the difference in mean times to assemble to be correct to within minute with a probability equal to .95, how many workers must be included in each training group? 16c3d JPG Fi
The management of a restaurant wants to determine a new advertising campaign has increased its mean daily income (net). The income for each of 50 business days prior to the campaigns beginning is recorded. After conducting the advertising campaign and allowing a 20-day period for advertising to take effect, the restaurant management records the income for 30 business days. These two samples will allow the management to make an inference about the effect of the advertising campaign on the restaurant's daily income. A summary of the results of the two samples is known in the table below; Before Campaign After Campaign ni 50 n2 30 %3D X1 Tshs 125,500 X2 133,000 S1 Tshs 21,500 S2 = 23,800 REQUIRED Do these samples provide sufficient evidence for the management to conclude that the mean income has been increased by the advertising campaign?
