Is there evidence to support the claim that catalyst 2 produces higher mean yield than catalyst 1? Use a=0.01. What is the appropriate hypothesis test? Right-tailed test Middle-tailed test O Left-tailed test Two-tailed test

Analyze data in SPSS using a dependent samples t-test • Imagine that we are interested in the difference in heart rate pre and post doing 30 seconds of jumping jacks. How might we test this question? (basic research design) Do the 4 steps of hypothesis testing (use the SPSS output sent): Step 1: • Write null hypothesis • Write research hypothesis Step 2:• Use a two-tailed test with alpha set to  = .05** • what is the critical region? Step 3: • what is the p-value? • what is the t-statistic? Step 4: • determine whether results are statistically significant • what do you conclude in general?

If we conduct a z-test and use the alpha level of p < .05 [and our test is 'non directional,' i.e, we consider values at both ends of the z-score distribution] the value that we calculate for the z-test has to fall inside                                 to be considered rare enough to be statistically significant.     5% of the lower values (tail of the curve) or 5% of the upper values in the other tail of the curve.     The middle 5% of the curve     2.5% of the lower values (tail of the curve) or 2.5% of the upper values in the other tail of the curve.     The middle 95% of the curve

What is the critical t score if you are testing a one-tailed hypothesis, α level of .05 with df = 35? Group of answer choices
