Homework Answers
Question 18:
30
The sample size of 30 is large enough when the population distribution is roughly bell shaped. That's why the minimum sample size will be 30.
Question 23:
0.012
since, we assume our default level of significance as 0.05. Here, only 0.012 is less than 0.05. That's why 0.012 could have been the P-value.
Hope this solution will help you to understand. If you are satisfied with the answer then please please give a like to this answer. Thank you.

Student loans: In an article from September 13, 2010, titled "Student Loan Default Rates Increase," the website ed.gov analyzes trends in default rates for student loans over time. For the year 2008, the default rate for graduates was 7%. Suppose that we select random samples from this population of graduates from 2008. For each sample we calculate the proportion who defaulted on their loans. What is the minimum sample size necessary for the sampling distribution to be approximately...

Question 6.3.14 In an article titled "Unilateral Nostril Breathing Influences Lateralized Cognitive Performance" that appeared in Brain and Cognition (1989), researchers Block et al. published results from an experiment involving assessments of spatial and verbal cognition when breathing through only the right versus left nostril. The subjects were 30 male and 30 female right handed introductory psychology students who volunteered to participate in exchange for course credit. Initial testing on spatial and verbal tests revealed the following summary statisticS Note...

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...
