Question

1. The larger the value of our obtained t:

the larger the probability of making a Type I error.

2.

Rejecting the null hypothesis for two independent groups means they are different in the population.

True

False

3. Compared to the .05 level of significance, the .01 level of significance:

means a higher probability of the obtained difference being a result of sampling error.

means a lower probability of the obtained difference being a result of sampling error.

means a perfectly normal distribution.

means a skewed distribution.

the larger the probability of making a Type I error.

2.

Rejecting the null hypothesis for two independent groups means they are different in the population.

True

False

3. Compared to the .05 level of significance, the .01 level of significance:

A.

means a higher probability of the obtained difference being a result of sampling error.

B.

means a lower probability of the obtained difference being a result of sampling error.


C.

means a perfectly normal distribution.


D.

means a skewed distribution.

Explanation / Answer

Q1.It is False. The larger the value of our obtained t: does not mean,  the larger the probability of making a Type I error.

Q2) yes, it is true. Rejecting the null hypothesis for two independent groups means they are different in the population.

Q3) Option B is Correct. means a lower probability of the obtained difference being a result of sampling error
