Question

[ MATCHCorresponding Letter to the number by Selecting the proper conclusion from the following list.

Assume that the null hypothesis is no difference or no mean difference.

[a] Reject the alternate hypothesis. We have good evidence that there is a significant difference.

[b] Do not reject the alternate hypothesis. We do not have enough evidence that there is a significant difference.

[c] Accept the alternate hypothesis. There is no evidence of a significant difference.

[d] Reject the null hypothesis. There is evidence of a significant difference.

[e] Accept the null hypothesis. There is no difference.

[f] Do not reject the null hypothesis. There is not enough evidence of a significant difference.
