Several students were tested for reaction times (in thousandths of a second) using their right and left hands. (Each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the subject.) Results from five of the students are included in the graph to the right. Use a 0.02 significance level to test the claim that there is no difference between the reaction times of the right and left hands. Click the icon to view the reaction time data table. What are the hypotheses for this test? Let be the Ho: Ha H₁: Ha ▼0 of the right and left hand reaction times. What is the test statistic? t=(Round to three decimal places as needed.) Identify the critical value(s). Select the correct choice below and fill the answer box within your choice. (Round to three decimal places as needed.) OA. The critical value is t=. OB. The critical values are t= + What is the conclusion? There enough evidence to warrant rejection of the claim that there is between the reaction times of the right and left hands.

The claim is that the proportion of adults who smoked a cigarette in the past week is less than 0.35 and the sample statistics include n =1600 subjects with 576 saying that they smoked cigarette in the past week .Find the value of the test statistics ?

A recent study evaluated how addicted teenagers become to nicotine once they start smoking. The response variable was the number of yes answers on a questionnaire called the Hooked on Nicotine Checklist (HONC). Of teenagers who had tried tobacco, the mean HONC score was 3.8 (s = 4.8) for the 143 females and 2.3 (s = 2.8) for the 171 males. Complete parts a through c below. ... (Round to four decimal places as needed.) What does the standard error indicate? A. The standard error describes the spread of the sampling distribution of x₁ - x2- OB. The standard error is the standard deviation of the sample for this study. OC. The standard error is the difference in standard deviations for the two populations. OD. The standard error is the standard deviation of the difference between x₁ - x₂- b. Find the test statistic and P-value for Ho: H₁ H₂ and Ha: H₁ H₂. Interpret, and explain what (if any) effect gender has on the mean HONC score. Use the significance level 0.05. The test statistic is…

You read a newspaper article that says that 74% of households in your town participate in a recycling program.  To test that statement at the 10% significance level, you randomly select 54 households in town and you find that 35 of them participate in the recycling program. Ho: P=0.74                  Ha:P=/ 0.74 Find the P-value.  Round your answer to 3 decimal places.
