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

Working alone, it would take Shandra 40 minutes to sand a table. To sand the same table, also working alone, it would takeKelly 1 hour. If they work together, the situation can be modeled by the following equation, where t is the time it would take tosand the table working together.1/40+1/60=1/tShandra claims it will take them about 50 minutes working together, because 50 is the mean of 40 and 60. Which bestdescribes Shandra's claim?

The amount of kerosene, in thousands of liters, in a tank at the beginning of any day is a random amount Y from which a random amount X is sold during that day. Suppose that the tank is not resupplied during the day so that x ? y, and assume that the joint density function of these variables is f(x,y) = 2 for 0 < x < y < 1. find the that the amount of kerosene sold is between 0.25 and 0.50 thousands liters given that the amount in the tank at the start of the day is 0.90 thousands liters. (Hint: f(x|y) = f(x,y) / fy(y) ).
