since it is tested for difference and not if one is higher/lower ; Correct hypothesis are:
null Hypothesis:μd | = | 0 |
alternate Hypothesis: μd | ≠ | 0 |

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 0.10 significance level to test the claim that there is no difference between the reaction times of the right and left hands....

A. B. The 95% confidence interval is _____ <μd< _____. (Round to two decimal places as needed.) What does the confidence interval suggest about farmer Joe's claim that type 1 seed is better than type 2 seed? A. Because the confidence interval only includes positive values and does not include zero, there is not sufficient evidence to support farmer Joe's claim. B. Because the confidence interval includes zero, there is sufficient evidence to support farmer Joe's claim. C. Because the...
I need help to write a nice introduction for experiment 6 please ( no hands write ) typing Thank you HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
