Use Sinclair’s work to answer the questions and complete the statements. How did Sinclair come up with the dimensions 1, 7 3 , and 5 3 in step 2? He multiplied the original dimensions by a scale factor of . What can Sinclair conclude about the effect on the trapezoid’s area from his comparison? The changes created an area times the original area.

Anull hypothesis states that the difference between 8 hours of sleep and 3 hours of sleep has no effect on the number of pictures a student will remember during a picture memory interface test (pmit). examining the mit database, an extremely small t-value of 0.1611 is found. this t-value is much smaller than the smallest t-value on the chart for p-value reference. from this information we can: select one: a. accept the null hypothesis because the p-value obtained shows that the difference between the two groups being tested is not statistically significant b. accept the null hypothesis because the p-value obtained was statistically significant c. reject the null hypothesis because of the p-value obtained d. reject the null hypothesis because the data obtained is statistically significant
