In a particular experiment to see if caffeine consumption has a statistically significant effect upon memory, a student found that the caffeine consumers scored a 97 while those who didn't consume caffeine scored an 89. the student also determined that t=2.39 and p=0.03. what can the student conclude? (a) there is not a statistically significant difference in scores between these two groups based solely on the high t-value(b) there is a statistically significant difference in scores between these two groups based solely on the low p-value (c) there is a statistically significant difference in scores between these two groups based solely on the large difference in means(d) not enough information is given(e) there is a statistically significant difference in scores between these two groups based solely on the high p-value

the correct answer is (B) There is a statistically significant difference in scores between these two groups based solely on the low p-value

Step-by-step explanation:

The p-value is the level of marginal significance within a statistical hypothesis test representing the probability of the occurrence of a given event. The p-value is used as an alternative to rejection points to provide the smallest level of significance at which the null hypothesis would be rejected. In this case the  small p-value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p-value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

at least two
