Example 3. The College of Engineering of a State University gives an entrance exam to incomingfreshmen. Those who got scores equal or higher than the set passing are accepted in the College. Theaverage score of the incoming freshmen was 80% before the implementation of K to 12 educationsystem. Due to this implementation, the entrance exam was suspended for two years and it is thoughtthat the quality of the first year students had diminished. However, with the vision, mission, goals andobjectives of the University and the College towards quality education, the Dean wants to determine ifthe quality of freshmen students has changed. He wants to know if it has improved or diminished so asmall random sample of 15 freshmen students and administers the same entrance exam. The averagescore is found to be 83% with a standard deviation of 5%. Determine whether the quality has changedusing 1% level of significance.

From the given information, Null Hypothesis: H0: μ=80% The quality has not changed. Alternative…

Suppose that I want to estimate the percentage of students who love statistics in California. How many students would I need to survey in order to have a margin of error that is less than 3%, assuming that I want to be 90% confident in the final results.
To get from Berkeley to the San Francisco airport (SFO) one can either take a shuttle van or drive. Either way, one must cross the San Francisco Bay Bridge. The shuttle van drops its passengers at the airport departure terminal. If one drives, he or she must park in a lot near the airport, then take a parking shuttle from the parking lot to the airport departure terminal. There is a 40% chance that the Bay Bridge will be congested with traffic. If it is, it takes 1.1 hours to drive to the parking lot. If not, it takes 40 minutes to drive to the parking lot. The parking shuttle runs every 10 minutes and takes 10 minutes to get to the airport departure terminal from the parking lot. Suppose it is equally likely that one must wait 0, 1, or 9 minutes for the parking shuttle once getting to the parking lot, and that the amount of time one must wait is independent of the amount of time it takes to drive to the parking lot from Berkeley. 2, If one takes the shuttle van from Berkeley directly…

A researcher is curious to see if the amount of time spent on social media influences how often friends meet in person to socialize. After their sample is selected the researcher asks the subjects on average how much time they spend on social media each day and then asks their subjects to keep track of how many times they meet in person with their friends to socialize and report back at the end of the month. What type of study design is this? The research obtains 100 participates who met with their friends in person at least 15 times in the last month to socialize and 100 participates who met with their friends in persons less than 15 times in the last month to socialize. Then the researcher asks the participants on average how many hours per day did they spend on social media during the month before. What type of study design is this? Options for both questions: Cohort, case-control, cross-sectional, clinical trial
The principal of Paul Revere High School bragged that his 2016 graduating class of 1500 students achieved impressive scores on their ACT exams. He announced that an “astounding” 36% of the class got a score of 29 or higher, 54% got a score of 21 to 28, and only 10% less than 21. You want to test whether these ACT results are really that astounding. You visit the ACT website to see that the national results are 34% getting a score over 28, 58% getting 21 to 28, and 8% less than 21. Test whether or not the principal is correct to brag that his proportions were more impressive than the national performance. Use an alpha of 0.05. So I kinda understand the question. I am mostly confused about how to determine the degree of freedom to get the critical value. Like I know the formula is d-C, and C is the number of categories in the word problem, but is there 3? Or am I just totally wrong?

A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. Compute the percentage of variance explained by the group differences for these data. Q: Percentage and variance explained = ?
Tuff Rubbers, a tire manufacturer, knows that 5% of the tires it produces are defective. To reduce the number of defective tires that make it to market, the manufacturer uses a special device to test each tire before shipping it out. The test will correctly detect a defective tire 97% of the time. However, the test will incorrectly indicate a good quality tire is defective 6% of the time. If the test indicates a tire is defective, the tire is recycled. Otherwise, the tire makes it to market. Let D represent the event a tire is defective, and T represent the event the test indicates a tire is defective. In each part of this question, express each probability only in terms of the events D and T and justify any computation by explicitly stating the formula you are using. (a) Express each of the three probabilities listed above in terms of the events D and T. (b) What percentage of tires are recycled? (c) What percentage of recycled tires are not defective? (d) What percentage of…

You have set a professional goal to become the head of your workplace’s Party Planning Committee. Your CEO has agreed that the role will be yours if you can inspire your team to create enough workplace goodwill that more than 60% of this year’s Holiday Party attendees participate in the ‘ugly sweater’ contest. When you see that 34 of the 47 attendees at the party have on some of the ugliest holiday sweaters you’ve ever seen, you think the new title is yours. However, the next day the CEO comes up to you and says she thinks it was just random chance that so many employees participated in the contest and she is going to hand your committee over to your arch-nemesis, Karen from finance. Claim your new title by proving her wrong! Run the correct test using a software and provide the information below. Use correct symbols and round answers to 3 decimal places. Test Statistic, Critical Value, p-value State your statistical decision (and justify it!)…
