Consider the StatKey output below that provides a bootstrap distribution for the difference in proportions: Use all provided information.  The normal approximation of this bootstrap distribution is: N(

Researchers from Gallup used a random sample of n = 1503 adults in the US who were asked whether they drove a car every day of the week.  The proportion who said “yes” was 0.62 with a margin of error of 0.04. What is the correct calculation for the interval estimate for the population proportion who drove a care every day of the week?

Researchers test the provided hypotheses about two variables: ‘Favorite type of Apple’ (Red Delicious, Granny Smith, Honeycrisp, Empire, Gala) and ‘Time Zone where you Live: ‘(Pacific, Mountain, Central, Eastern) when based on a sample of n = 200 U.S. adults. H0: There is no association between favorite type of apple and time zone where you live. Ha: There is an association between favorite type of apple and time zone where you live Assume the researchers calculated a p-value of 0.246.  What is the correct conclusion for this hypothesis test using a significance level of 0.05?

Researchers surveyed n = 25 stat 200 male students to determine if they consume 3 or more alcoholic beverages per week. Their goal was to see if more than 50% of male students consume 3 or more alcoholic beverages per week. The relevant sample statistic is 0.60 (60%) with a standard error of 0.10.  The p-value is 0.159. Correctly complete the p-value interpretation below: The chance of seeing a test statistic of = or any value is , if in fact the hypothesis is true.

Research Question:  What percent of Stat 200 students regularly complete the lab worksheet prior to their scheduled lab class?    The parameter of interest is a . To answer this question, we should .  

Research Question: Are dog owners more likely to be extroverted when compared to cat owners? The parameter of interest is a . To answer this question, we should .  

Consider the three situations below: Situation A: Compare the proportion of CATA bus drivers who have seniority status to the proportion of CATA bus drivers who have been employed for less than one year Situation B: Compare the proportion of PSU alumni who have given back to the university to the proportion of PSU alumni who have never given back to the university Situation C: Compare the proportion of Google employees who work remotely to the proportion of Facebook employees who work remotely. Match each situation to the correct comparison:

Does reintroducing wolves into an ecosystem improve the overall health of the system (as measured by species richness)? A team of ecologists tested this on 30 different forested parks. Assume the researchers performed an experiment and calculated a p-value of 0.019.  Complete the statements below: Using a significance level of 0.05, the researchers should the null hypothesis. It is possible that they have committed a type error.
