Also, using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2009 scores. Report the t-obt, df, and p-values. Would you reject the null hypothesis that the 2009 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?

Patient satisfaction. Scores derived from a patient satisfaction survey are Normally distributed with μ = 50 and σ = 7.5, with high scores indicating high satisfaction. You want to test H0: μ = 50 based on a sample of n = 36 from the particular patient group showing x¯x¯= 48.8. a) What is the one-sided alternative hypothesis for this test? b) Calculate the z-statistic for the test. c) Interpret the p-value.
Are seatbelts effective at saving lives? We wish to examine whether or not the use of seatbelts reduces fatalities at the alpha = 0.05 level of significance. Let p N represent the proportion of non-seatbelt wearing passengers who were involved in a crash and died and represent the proportion of seatbelt wearing passengers who were involved in a crash and died. 1. Which would be correct hypotheses for this test?
