You take a random sample of size 30 and conduct a hypothesis test at the 5 % level of significance . If instead , you take a random sample of size 50 and conduct the same hypothesis test at the same 5 % level of significance , what can you say about the probability of a type I and type II error (all else being equal ) ? A. P (Type I errror ) decreases and P (Type II error...

1) You conduct a hypothesis test on an experimental drug K-2090 and you observe a test statistic (mean blood pressure difference) value of 0.9 calculated from a sample with size n = 100. This test statistic had a corresponding p-value of 0.064 which was greater than the significance level, and therefore failed to reject the null hypothesis. What will happen to the p-value if you observe the same test statistic for a sample of n = 10,000? a May either...

A random sample of size 295 has x=104. The significance level ? is set at 0.05. The P-value for testing H0: ?=100 against Ha: ??100 is 0.057. Identify all the incorrect statements below regarding this P-value of 0.057. (Select all that apply.) The probability of Type I error equals 0.057. If H0 is true, the probability obtaining a sample mean that would show at least as much evidence against H0 as the observed sample mean is 0.057. The probability that...

1. Suppose you are going to conduct a two tail test concerning the population mean. Suppose that you do not know what the population standard deviation is and that you have a sample of 55 observations. If you are going to conduct this test at the .01 level of significance what is the critical value? Be sure to enter a positive number and answer to four decimal places. 2.The p-value is? Group of answer choices: the probability of a Type...
