Technology Activity 10

Q For the Technology Activity 10, you will be submitting the results of three different, two-sample hypothesis tests. You will use each of the three technologies, TI-84, Excel, and Online Apps. to complete the activity. You must use each technology once. Sample exercises for each of the three different tests can be found in the Performing Two Sample Hypothesis Tests content page. You will want to view this content page first. Make sure that you can use each technology to perform a two sample hypothesis test. All three exercises are to be submitted in a single MS Word document with the required questions answered in full detail. You are to indicate which technology you used for each exercise and provide a screen capture of the results. Each problem is worth 10 points. Section 9.1 – Hypothesis Test for Mean Differences: Paired Data 1. State the null and alternate hypothesis. 2. State the significance level, or ? (alpha) 3. Using either the Critical Value or P-Value approach, state the Critical Value or P-Value. 4. State 'Reject' or "Fail to reject' the null hypothesis. 5. Interpret your results of the hypothesis test. 6. Provide a screen capture of the technology used. Section 9.2 – Hypothesis Tests for Two Means: Independent Data The statistical summary is provided for you. 1. State the null and alternate hypothesis. 2. State the significance level, or ? (alpha) 3. Using either the Critical Value or P-Value approach, state the Critical Value or P-Value. 4. State 'Reject' or "Fail to reject' the null hypothesis. 5. Interpret your results of the hypothesis test. 6. Provide a screen capture of the technology used. Section 9.3 – Hypothesis Test for Two Proportions 1. State the null and alternate hypothesis. 2. State the significance level, or ? (alpha) 3. Using either the Critical Value or P-Value approach, state the Critical Value or P-Value. 4. State 'Reject' or "Fail to reject' the null hypothesis. 5. Interpret your results of the hypothesis test. 6. Provide a screen capture of the technology used. PreviousNext

(1) µ_1: Mean of weight method µ_2: Mean of groove method H_o:µ_1=µ_2 H_a:µ_1?µ_2 Significance level ?=0.05 we perform our test based on this. Since the test is two tailed, we have ?/2=0.025 From the Excel we get the critical values as Since the degrees of freedom is 10 that is n-1=11-1=10 -2.228 and 2.228 since they are two tailed tests
