Question

1] An open-ended bin (e.g., "50 and over") might be seen in a frequency distribution when:

Select one:

a. some data values are not integers.

b. data values are nonnumerical.

c. extremely large data values exist.

d. some data are missing.

2] Which of the following statements is correct?

Select one:

a. Increasing will make it more likely that we will reject H0, ceteris paribus.

b. Doubling the sample size roughly doubles the test statistic, ceteris paribus.

c. A higher standard deviation would increase the power of a test for a mean.

d. The p-value shows the probability that the null hypothesis is false.

1. When extremely large data values exist and you want dont want to make too many classes then open ended bin will be used. Option c is correct.

As the increases, rejection region also increases so it more likely that we will reject H0. So statement (a) is correct.
