Treating the 2015 Tobacco rate data as a sample, construct a 95% confidence interval for the mean tobacco rate for males and for females. Interpret each interval. Does it appear that males use tobacco at a higher rate than females? Justify your answer, using the confidence intervals in your explanation. Construct the same confidence interval for males at the 99% confidence level. Compare to the male 95% confidence interval from the previous question. What happened to the interval when the confidence level increased? Explain why.

We constructed a 95% confidence interval for a population mean. Which of the following would cause the confidence interval to become wider. Select all that apply. This question does not break the honor code and is not graded. Just practice on topics
2.3 The width of a confidence interval is a measure of its precision. The narrower the confidence interval, the more precise is the interval estimate, and vice versa. Describe any three aspects that influence the precision of the width of a confidence interval of a single population mean.

Hi, may you please help me with the following: The purpose of this assignment is to apply hypothesis tests to the case of Bayview University. Use the dataset below and read the case thats attached, use descriptive statistics to summarize the data and comment on your findings. Answer the following 3 questions. Develop 95% confidence interval for the proportion of all students, the proportion of male students, and the proportion of female students who were involved in some type of cheating. Conduct a hypothesis test to determine whether the proportion of business students at Bayview University who were involved in some type of cheating is less than that of business students at other institutions by the Chronicle of higher education.

Two statistics teachers both believe that each has the smarter class. To put this to the test, they give the same final exam to their students. A summary of the class sizes, class means, and standard deviations is given below: ?1=41,?2=40,?¯1=82.4,?¯2=84,?1=15.5?2=18n1=41,x¯1=82.4,s1=15.5n2=40,x¯2=84,s2=18 Is there evidence, at an ?=0.01α=0.01 level of significance, to conclude that there is a difference in the two classes? (Assume that the population variances are equal.) Carry out an appropriate hypothesis test, filling in the information requested. A. The value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form (−∞,?)(−∞,a) is expressed (-infty, a), an answer of the form (?,∞)(b,∞) is expressed (b, infty), and an answer of the form (−∞,?)∪(?,∞)(−∞,a)∪(b,∞) is expressed (-infty, a)U(b, infty). B. The rejection region for the standardized test statistic:
