During the 2013 season, Major League Baseball took steps to speed up the play of baseball games in order to maintain fan interest. The average duration of a game from a sample of 60 games played during the summer of 2012 was 2 hours and 52 minutes. The average duration of a game from a sample of 50 games played during the summer of 2013 was 2 hours and 46 minutes. For the purposes of this question, let 2013 games be population 1. 1a. A research hypothesis was that the steps taken during the 2013 season would reduce the population mean duration of baseball games. Formulate null and alternative hypotheses. 1b. What is the point estimate of the reduction in the mean duration of games during the 2003 season?
2.24 Exit poll: Edison Research gathered exit poll results from several sources for the Wisconsin recall election of Scott Walker. They found that 52% of the respondents voted in favor of Scott Walker. Additionally, they estimated that of those who did vote in favor for Scott Walker, 36% had a college degree, while 42% of those who voted against Scott Walker had a college degree. Suppose we randomly sampled a person who participated in the exit poll and found that he had a college degree. What is the probability that he voted in favor of Scott Walker?(please round to 4 decimal places)
A study of fox rabies in a country gave the following information about different regions and the occurrence of rabies in each region.

In a large clinical trial, 399,884 children were randomly assigned to two groups. The treatment group consisted of 201,068 children given a vaccine for a certain disease, and 26 of those children developed the disease. The other 198,816 children were given a placebo, and 91 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Complete parts (a) through (d) below. a. Assume that a 0.10 significance level will be used to test the claim that p₁
A study of fox rabies in southern Germany gave the following information about different regions and the occurrence of rabies in each region.

In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.Use a calculator with sample mean and sample standard deviation keys to find x1 and s1 in region I, and x2 and s2 in region II.

An experiment is conducted to study the energy requirements of three physical activities: running, walking and cycling. Eight subjects are selected at random. It is thought that metabolic differences among the subjects might affect the kilocalories required for a given activity, hence, the experiment is done by taking into account of these differences. Each subject is asked to run, walk and cycle a measured distance, and the kilocalories expended per kilometre is determined for each subject during cach activity. The activities are run in a random order with time for recovery between activities. Subject Running Walking Cycling 0.7 1 1.4 1.1 2 1.5 1.2 0.8 3 1.3 1.3 0.7 0.8 1.8 4 1.7 0.7 0.1 5 6 1.6 1.5 1.2 0.7 0.4 0.6 7 1.7 1.1 8 2.0 1.3 a) State a statistical model and its assumptions. b) By using an ANOVA test, interpret whether there are differences in energy requirements for the three activities. Use a = 0.05. c) By using an ANOVA test, interpret whether there are differences in…

A random selection of volunteers at a research institute have been exposed to a typical cold virus. After they started to have cold symptoms, 15 of them were given multivitamin tablets formulated to fight cold symptoms. The remaining 15 volunteers were given placebo tablets. For each individual, the length of time taken to recover from the cold is recorded. At the end of the experiment the following data are obtained.
