1. Peter Dinklage a student of BUS 173, was not absent on 5 July. However. due to evidence of the contrary, I marked him absent in that particular class. Considering the 2 types of errors-I most likely made a a. Type i error as I did not reject a false null b. Type i error as I rejected a true null c. Type ii error as I did not reject a false null d. Type il error as I rejected a true null 2. In a two population hypothesis test where the population standard deviation is unknown and assumed to be unequal, the (independent) sample sizes are n1= 11 and n2= 14. The sample standard deviations are 10 and 8 respectively, the degrees of freedom is- a. 18.91 b. 19.00 c. 18.00 d. 23.00 3. A manufacturer advertises that the contents in their detergent box on average weigh at least 16 ounces. The standard deviation of the weight of all such boxes is 0.4 ounces. A random sample of 16 boxes yields a sample mean weight of 15.84 ounces. Testing at the 10% significance level whether this claim is…

Complete all six steps of hypothesis tesitng. A college president wanted to know how 10-year-after-graduation salaries for academic majors (English, psychology, math, etc.) compared to salaries for career-oriented majors (business, engineering, computer science, etc.). She matched 84 academic majors at her college with 84 career-oriented majors on the basis of SAT scores and GPA. She found MAcademic = $59,250, MCareer =$61,000, sD = 9,500. Analyze and interpret.
