(a) For the same data and null hypothesis, is the P-value of a one-tailed test (right or left) larger or smaller than that of a two-tailed test? pick one The P-value for a one-tailed test is smaller because the two-tailed test includes the area in both tails. The P-value for a one-tailed test is larger because the two-tailed test includes the area in only one tail. The P-value for a one-tailed test is larger because the two-tailed test includes the...

Answer
Option:
(fail to reject. Reject) Ho because the P-value
is (greater than. Less than or equal to)
the significance level. There (is not. Is)
sufficient evidence that the mean time interval has charged
Listed below are time intervals (min) between eruptions of a geyser. Assume that the "recent" times are within the past few years, the "past" times are from around 20 years ago, and that the two samples are independent simple random samples selected from normally distributed...

A 0.01 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender selection, the proportion of baby girls is less less than 0.5. Assume that sample data consists of 45 girls in 100 births, so the sample statistic of StartFraction 9 Over 20 EndFraction 9 20 results in a z score that is 1 standard deviation below below 0.
