Using traditional methods it takes 105 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has beenproposed. A researcher believes the new technique may reduce training time and decides to perform a hypothesis test. After performing the test on 50 students, theresearcher fails to reject the null hypothesis at a 0.02 level of significance.What is the conclusion?

In a hypothesis test, the null hypothesis is the statement being tested. In this case, the null…

The magazine Tech Worx reported that 88% of software engineers rate the company they work for as "a great place to work." As a veteran headhunter, you claim the percentage given in the report is not correct. In a survey of 210 randomly chosen software engineers, 186 rated the company they work for as "a great place to work." Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support your claim that the proportion, p, of all software engineers who rate the company they work for as "a great place to work" is not 88%. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test. H: I (b) For your hypothesis test, you will use a Z-test. Find the values of np and n (1-p) to confirm that a Z-test can be used. (One standard is that np 2 10 and n(1-p) > l0 under the assumption that the null hypothesis is true.) Here n is the sample size and p is the population proportion you are…
A local coach wants to see if training in light rooms or dark rooms impacts athlete performance. With the single team, the coach tries training in different conditions and takes measurements. She ran her analysis in Microsoft Excel and received the following output table. If the P value is less than 0.05, the null hypothesis may be rejected. Based on the data table, what decision should the coach make about the hypothesis? Coach should reject the null hypothesis. Coach should fail to reject the null hypothesis. Coach should accept the null hypothesis. Coach does not have enough information to decide.
When asked what it means for the result of a hypothesis test to be practically significant (or practically important), Tatum says this means that the P-value is small and the null hypothesis has been rejected. what is wrong about this?

A university has decided to introduce the use of plus and minus grading as long as there is evidence that 60% of the faculty is in support of this change. Write an appropriate null hypothesis and alternate hypothesis to test if the proportion is greater than 60%.
Show your complete solution II. Use an appropriate statistical tool to test the hypothesis. Use the stepwise method of hypothesis testing. 3.
