Is there an association between whether adults eat breakfast and whether they own a pet? To investigate,researchers select a random sample of 75 adults and asked them if they ate breakfast and if they owned a pet. Theresearchers would like to determine if there is convincing evidence of an association. Let a = 0.05. What are thehypotheses for this test?O Họ: There is an association between whether adults eat breakfast and whether they own a pet.Hạ: There is no association between whether adults eat breakfast and whether they own a pet.O Ho: There is no association between whether adults eat breakfast and whether they own a pet.Hạ: There is an association between whether adults eat breakfast and whether they own a pet.O Họ: There is no difference in the distribution of whether adults eat breakfast and whether they own a pet.Hạ: There is a difference in the distribution of whether adults eat breakfast and whether they own a pet.O Ho: There is a difference in the distribution of whether adults eat breakfast and whether they own a pet.Hạ: There is no difference in the distribution of whether adults eat breakfast and whether they own a pet.

Stay safe and healthy. Exercise: Apply the procedure in testing the hypothesis. A survey was conducted at a community college of 102 randomly selected students who dropped a course in the current semester to learn why students drop courses. Personal drop reasons include financial, transportation, family issues, health issues, and lack of child care. Course drop reasons include reducing ones load, being unprepared for the course, the course was not what was expected, dissatisfaction with teaching, and not getting the desired grade. Work drop reasons include an increase in hours, a change in shift, and obtaining full-time employment. Test whether gender is independent of drop reason at the 1% level of significance.

When two births are randomly selected, the sample space for genders is bb, bg. gb, and gg. Assume that those four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births. Does the mean of the sample proportions equal the proportion of girls in two births? Does the result suggest that a sample proportion an unbiased estimator of a population proportion? For the entire population, assume the probability of having a boy is the probability of having a girl is , and this is not affected by how many boys or girls have previously been born. 2 Determine the probabilities of each sample proportion.
