A college entrance exam company determined that a score of 24 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, thecompany recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean mathscore of 24.6 on the college entrance exam with a standard deviation of 3.3. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is,are they scoring above 24 on the mathematics portion of the exam?

A college entrance exam company determined that a score of 23 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 250 students who completed this core set of courses results in a mean math score of 23.2 on the college entrance exam with a standard deviation of 3.7. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they scoring above 23 on the mathematics portion of the exam?

A USA based cable broadband company wants to investigate whether it's east coasts customers have a higher average customer satisfaction score than compared to it's west coast customers. The customer survey asks for a score between 1 and 5, with 1 being poor and 5 being excellent. 174 east coast customers are surveyed, and the sample mean is 3.35 with a sample standard deviation of 0.51. For the west coast, 355 customers are surveyed, and the sample mean is 3.24 with a sample standard deviation of 0.52.
The manager of the shipping department of a mail-order operation located in New York advertises that the length of time it takes for customers in California to receive their orders is 8 days. However, the office has been receiving complaints from customers in California stating that orders do not arrive in time advertised. To learn more about this potential problem, the manager chose a random sample of 15 orders. The sample mean of delivery times was 12.25 days. The sample standard deviation was 3.67 days.The average time it takes for all California customers to receive their orders is to be estimated with a 99% confidence interval. a. The ? − or ? −value that should be used to construct this interval is b. The margin of error is equal to

The University of Montana admission standards require students to have an ACT score of at least 22.We know that Montana ACT scores are normally distributed with a mean of 20.1 and standarddeviation of 4. If we ask a random sample of 100 students who took the ACT, how many would be expected toqualify for admission to UM?

According to a recent study published by the American Statistics for Educators Journal, statistics students spend, on average, 80 minutes a week playing video games. A certain instructor of statistics at WCC believes that WCC students spend less than this amount of time playing video games per week. To test his belief, he randomly samples 31 students and finds the sample mean to be 72 minutes with a standard deviation of 35 minutes. At the 0.05 level of significance, is there evidence to suggest that WCC students spend less than 80 minutes a week, on average, playing video games? Use the p-value approach. Define the parameter we are testing and setup a hypothesis to test the see if the statistics instructor is correct: Calculate the test statistics for this hypothesis test. What is the p-value for this hypothesis test?
An ordinary traveler claims that the average difference between the plane fares of all trips from the Philippines to a certain destination in the two airlines is significantly different. To validate this claim, 145 trips have been randomly selected from the first airline, which gave a mean fare of PHP 23,502.71 with a sample standard deviation of PHP 4,853.39. On the other hand, 123 trips are chosen at random from the second airline, which provided a mean fare of PHP 21,884.09 with a sample standard deviation of PHP 4,987.73. Assume that the populations are normally distributed, and the standard deviations for both populations are equal. At ? = 0.01, indicate whether or not there is sufficient evidence to support the traveler’s claim
The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures students' study habits and attitudes toward school. The survey yields several scores, one of which measures student attitudes toward studying. The mean student attitude score for college students is about 30, and standard deviation is about 12. A researcher in the Philippines is concerned about the declining performance of college graduates on professional licensure and board exams. She suspects that poor attitudes of students are partly responsible for the decline and that the mean for college seniors who plan to take professional licensure or board exams is less than 30. She gives the SSHA to an SRS of 144 college seniors in the Philippines who plan to take professional licensure or board exams. Suppose we know that the student attitude scores in the population of such students are Normally distributed with standard deviation σ = 12. (a) We seek evidence against the claim that μ = 30. What is the…
The Sony Corporation produces an AM/FM Walkman that requires two AA batteries. The mean life of these batteries is 35.0 hours. The distribution of the battery lives closely follows the normal distribution with a standard deviation of 5.5 hours. As a part of their testing programme, Sony tests samples of 25 batteries. a)What fraction of the sample will have a mean useful life of greater than 34.5 hours? b)What fraction of the sample will have a mean useful life between 34.5 and 36.0 hours?
Assume a media agency reports that it takes television streaming service subscribers in the U.S. an average of 6.60 days to watch the entire first season of a television series, with a standard deviation of 4.21 days. Scarlett is an analyst for an online television and movie streaming service company that targets to the 18-50 age bracket. She wants to determine if her company's customers exhibit shorter viewing rates for their series offerings. Scarlett plans to conduct a one-sample ?-z-test, with significance level of ?=0.05α=0.05, to test the null hypothesis, ?0:?=6.60 daysH0:μ=6.60 days, against the alternative hypothesis, ?1:?<6.60 days.H1:μ<6.60 days. The variable ?μ is the mean amount of time, in days, that it takes for customers to watch the first season of a television series. Scarlett selects a simple random sample of 740 customers who watched the first season of a television series from the company database of over 25,000 customers that qualified. She compiles the…
A college admissions officer believes that students enrolling from Shawnee school District have higher SAT scores than those who enroll from West River School District. A sample of 30 students from each district is selected. The average SAT score for the group from the Shawnee district is 656 with a standard deviation of 100. The average SAT score for the group from the West River district is 560 with a standard deviation of 90. Is the belief of the admissions officer substantiated?
