Past experience indicates that the time required for high school seniors to complete a standardized test is a normal random variable with a mean of 35 minutes. If a random sample of 40 high school seniors took an average of 33.2 minutes to complete this test with a standard deviation of 4.3 minutes, can it be concluded that the average time is different from 35 minutes? Use 0.10 level of significance. 1. State the null and alternative hypotheses: Options: { = +*sz<>} Ho: µ Blank 1 35 minutes Ha: u Blank 2 35 minutes 2. Which of the hypotheses is the claim to be tested? Blank 3 Options: { Ho, Ha } 3.
