A neuroscientist wants to know if physical exercise changes reaction speed in elderly people. A total of 14 older volunteer participants were found. One sample of n = 7 subjects received an exercise treatment, while the second sample (n = 7) of participants were given stretching lessons for the same amount of time per week. Reaction speed was tested on a computer program after six weeks of treatment. Reaction speed was measured in milliseconds. Data shown below. What is the type of statistical test you could use on these data? _____________________ Why this test? ___________________________________________________________ What is the I.V.? ___________________ What is the D.V.? ______________________ Use the data below to fill in the blanks to compute your tcalculated. stretch group exercise group nstretch = ____ dfstretch = _____ nexercise…
Recently, Goran ran for president of the local school board. Of those who voted in the election, 80% had a high school diploma, and the other 20% did not. Goran got 70% of the vote of those with high school diplomas, while he got only 15% of the vote of those without high school diplomas. Let D denote the event that a randomly chosen voter (in the school board election) had a high school diploma and D denote the event that a randomly chosen voter did not have a high school diploma. Let V denote the event that a randomly chosen voter voted for Goran and V denote the event that a randomly chosen voter did not vote for Goran. Fill in the probabilities to complete the tree diagram below, and then answer the question that follows. Do not round any of your responses. (If necessary, consult a list of formulas.)

A popular theory is that presidential candidates have an advantage if they are taller than their main opponents. Listed are heights (in centimeters) of randomly selected presidents along with the heights of their main opponents. Complete parts (a) and (b) below. Height (cm) of President 185 170 179 191 194 179 9 Height (cm) of Main Opponent 170 184 174 166 194 182 Identify the test statistic. t= 0.57 (Round to two decimal places as needed.) Identify the P-value P-value = 0.286 (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is greater than the significance level, fail to reject the null hypothesis. There is not sufficient evidence to support the claim that presidents tend to be taller than their opponents. b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to the same conclusion reached in part (a)? The confidence interval…
Over the past 10 years, contestants at the county fair hotdog eating contest averaged 125 hotdogs within the 1 minute time frame. Due to Covid19 restrictions, there were only 15 contestants who ate an average of 122 hotdogs. s=6.5 We're interested in finding out if there is significant change in hotdog eating. Use the hypothesis that H0: µ=125, Ha: #125. What is the SE? 10.9 1.7 6.5 8.3
