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 )
decreases
B. P (Type I errror ) stays the same and P(Type II error )
increases .
C. P(Type I errror ) decreases and P (Type II error ) increases
D. P(Type I errror ) stays the same and P(Type II error )
decreases
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 ,
P(Type I errror ) decreases and P (Type II error ) increases...hence C is the answer...
Justification--
The larger probability of rejecting the null hypothesis decreases the probability of committing a type II error while the probability of committing a type I error increases....and vice versa...
Note-if there is any understanding problem regarding this please feel free to ask via comment box ..thank you

answer please can simplify process 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 Il error (all else being equal)? O A. P(Type I error) stays the same and P(Type Il error) increases B....
When conducting a hypothesis test for a given sample size, if the probability of a Type I error decrease, the the A. probability of incorrectly not rejecting the null hypothesis decreases. B. probability of incorrectly not rejecting the null hypothesis increases. C. probability of incorrectly rejecting the null hypothesis increases. D. probability of type II error decreases.
Question 21 (4 points) For a hypothesis test about a population proportion or mean, if the level of significance is less than the p- value, the null hypothesis is rejected. (Ch10) True False Question 22 (4 points) Everything else being constant, increasing the sample size decreases the probability of committing a Type II error. (Ch10) True False The power of a statistical test is the probability of not rejecting the null hypothesis when it is true. (Ch10) True False Question...
Question 1 1 pts In classical hypothesis testing, what happens to the probability of Type II Error as we increase the significance level of the test (a)? P(Type II Error) Decreases P(Type II Error) Increases P(Type II Error) Stays the Same
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...
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...
1. You want to test whether you can reject the null hypothesis that a population mean is greater than or equal to 10. To do this, you collect a random sample of size 500 from the population, and you calculate that the sample mean and sample standard deviation are 8.6 and s, respectively. Which of the following is true? a. If s is any value between 11 and 13, you can reject the null hypothesis at the 5% significance level....
5. We conduct a test of hypothesis using a significance level of 0.05. This implies (a) the test has a 5% chance of H, being true. (b) the test has a 95% chance of a type II error. (c) the test has a 5% chance of being true. (d) none of the above.
A simple random sample of size n from a finite population of size N is a sample selected such that each possible sample of size a. n has a probability of 0.05 of being selected. b. N and n have the same probability of being selected. c. n has a probability of 0.5 of being selected. d. n has the same probability of being selected. You are __________ to commit a Type I error using the 0.05 level of significance...
One personality test available on the World Wide Web has a subsection designed to assess the "honesty" of the test-taker. After taking the test and seeing your score for this subsection, you're interested in the mean score l among the general population on this subsection. The website reports that u is 145, but you believe that u is greater than 145. To do a statistical test, you choose a random sample of 100 people and have them take the personality...
