According to the Pew Research Center, 14% of adults rate basketball as their favorite sport to watch. Your boss believes this proportion may be higher among adults under age 35, and wants you to collect evidence to see if this is true. Your boss is comfortable with the probability of a Type I error being 0.05. You survey 60 adults under age 35, and find that 23% of them rate basketball as their favorite sport. Conduct a hypothesis test and state your conclusion.

Past studies have indicated that the percentage of smokers was estimated to be about 34%. Given the new smoking cessation programs that have been implemented, you now believe that the percentage of smokers has reduced. You randomly surveyed 2483 people and found that 781 smoke. Use a 0.05 significance level to test the claim that the percentage of smokers has reduce. Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places. Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places.e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places.
A researcher wants to determine if there is a significant difference in the amount of time it takes a US adult to read a 400-word article when an individual is given either a paper or digital version. The sample consists of 64 select voting adults in which each adult experiences both treatments. The researcher required each individual to read the paper version first. The sample mean of the differences was 23.25 seconds. and the standard deviation of the difference was 4.97.

The preeminent basketball philosopher Rasheed Wallace popularized the phrase, "Ball don't Lie." This phrase means that if a foul was called incorrectly, the free-throw shooter is more likely to miss their shots. (We can think of this as a sort of Basketball Karma.) Due to the recent "Last Two Minute Report," we now have some data to test this claim. Of the 177 free throws awarded incorrectly, the shooter made 78.5%. Use this information to test the claim, with a .05 level of significance, that the percentage of made free throws after an incorrect foul call is less than 80%, which is the FT Percentage for an average NBA player. Round your answers to three decimal places or to the nearest tenth of a percent. (e.g. .021 or 2.1%) For credit, the hypothesis test must contain: 1) Claim in terms of the appropriate parameter (e.g. LaTeX: \mu=\:4.5\:miles) 2) Null and alternative hypothesis 3) Sample evidence used 4) Test stat (z or t) , p-value and direction of test.

Angela and Karissa are two friends who say they have no previous knowledge of statistics. They are going to take a placement test to see if they should start at the introductory level or not. The placement test is a multiple-choice test with 93 questions. Each question has 4 multiple-choice options with exactly one correct answer. What is the expected number (mean) of correct answers if a student were to randomly guess? (Do not round) What is the standard deviation for the number of correct answers if a student were to randomly guess? (Round to two decimal places) The usual number of correct answers, if a student were to randomly guess, would be to . (Round to the nearest whole number that would be within the interval.)

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat. Before opening the data, what would you hypothesize about this research question? Open the data set. Before running any statistical analyses, glance through the data. Do you think that your hypothesis will be supported? Conduct descriptive analyses and report them here. Conduct a one-way ANOVA.

A statistical program is recommended. The Condé Nast Traveler Gold List provides ratings for the top 20 small cruise ships. The data shown below are the scores each ship received based upon the results from Condé Nast Traveler's Annual Readers' Choice Survey. Each score represents the percentage of respondents who rated a ship as excellent or very good on several criteria, including Shore Excursions and Food/Dining. An overall score was also reported and used to rank the ships. The highest ranked ship, the Seabourn Odyssey, has an overall score of 94.4, the highest component of which is 97.8 for Food/Dining.
