Question

Preliminary data analysis indicate that it is reasonable to use a t-test to carry out the specified hypothesis test. Perform the t-test using the critical-value
approach.
Use a significance level of a=0.05 to test the claim that u = 35.8. The sample data consists of 10 scores for which x =44.2 and s = 7.3.
Ho : u+35.8
O:u= 35.8
Test statistic: t= 3.64. Critical values: t =±2.262. Reject H,: u= 35.8.
There is sufficient evidence to support the claim that the mean is different from 35.8.
Ho : u= 44.2
H:u=44.2
Test statistic: t= 3.64. Critical values: t= ±2.262. Reject H: u= 44.2.
There is sufficient evidence to support the claim that the mean is different from 44.2.
H: u=44.2
H: u=44.2
Test statistic:1= 3.64. Critical values: t = ±2.262. Reject H: u = 44.2.
There is sufficient evidence to support the claim that the mean is different from 44.2.
H:u= 35.8
Hu= 35.8
Test statistic:t=3.64. Critical values: 1= ±2.262. Reject H: u= 35.8.
There is sufficient evidence to support the claim that the mean is different from 35.8.

A data set includes data from 500 random tornadoes. The display from technology available below results from using the tornado lengths (miles) to test the claim that the mean tornado length is greater than 2.7 miles. Use a 0.05 significance level. Use the display to identify the null and alternative hypotheses, test statistic, and P-value. State the final conclusion that addresses the original claim.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
