5. It is claimed that the proportion of high school athletes who go on to play sports in college is 0.08. Believing this claimed value is incorrect, a researcher surveys a random sample of former high school athletes and finds that the proportion who went on to play sports in college is 0.07. When a hypothesis test is conducted at a significance (or alpha) level of 0.10, the P-value is found to be 0.06. What decision should the researcher make based on the results of the hypothesis test? 1. The null hypothesis should be rejected because 0.06 is less than 0.10. 2. The null hypothesis should be rejected because 0.06 is less than 0.07. 3. The null hypothesis should be rejected because 0.06 is less than 0.08. 4. The null hypothesis should be rejected because 0.07 is less than 0.08. 5. The null hypothesis should not be rejected.
2. When we carry out a 1-sample hypothesis test for the mean, one of the ways that we can check for normality is to look at the normal plot. How do we know if our normality assumption is satisfied by looking at the normal plot? Be as specific as possible.
Meth Barie's ice cream shop wants to decide whether to introduce a new ice cream flavor. They randomly selected 15 customers at their downtown Denton location to rate this new flavor. The rating is on a scale of 1 to 5, with 1 being 'not interested' and 5 being 'strongly interested'. Meth Barie's will approve the new flavor if the true mean rating is over 4.0. What is the Null hypothesis for testing whether the new ice cream should be approved?
following hypothesis test for matched data: Но : ld H1 : Hd + 0 For a sample of 18, it was found that d = 2.9 and sa = 3.56.
