use Part 1 that I solved to answer part 2 of the questions.

. State the alpha (a) level. rand X error before and after maintenance The alpha (a) level will be .05 Brand X Brand X Altimeter error Altimeter error before after adjustment adjustment. calibration calibration . Describe what you are comparing. As each brand is assessed twice, the comparison groups are claimed to be independent, thus we are using matched samples to compare the results. . State your hypothesis in a sentence For this chart, we will be using a two-tailed test because the hypothesis is non directional. As for Alternate Hypothesis - the true population differences are not equal to zero (ud). Null Hypothesis - Zero is the true difference in population (ud). . Indicate the appropriate f-test that you will use to evaluate your hypothesis The T-test utilized will be the matched pair t-test. t = (30 - ud)/[sa/vn].. State the hypothesis in a sentence {for example}: The average body temperature of people in our class is 93.6 degrees Fahrenheit. . Express that idea using scientic notation notah'on [For example: A one-sample test for temperature would read}: Null Hypothesis - Hg.- p = '3'EL6rAlternate Hypothesis - HA: p a: 93.6 . Appropriate t-test used to evaluate the hypothesis . Alpha {a} level . F-yalue . State in a sentence or two whether the hypothesis is rejected or if there is not enough evidence to reject the null hypotheses and what the results mean; Also, submit the Excel le used to run your tests
