Surface area of the base = 4^2 = 16 units^2.
Area of each triangular side = 1/2 * 4 * 3 = 6 unts^2
Total surface area of the pyramid = 16 + 4 * 6 = 40 unit^2 (answer)
Answer:
Nice. What is the question?
Step-by-step explanation:
Answer:
Null hypothesis is: U1 - U2 ≤ 0
Alternative hypothesis is U1 - U2 > 0
Step-by-step explanation:
The question involves a comparison of the two types of training given to the salespeople. The requirement is to set up the hypothesis that type A training leads to higher mean weakly sales compared to type B training.
Let U1 = mean sales by type A trainees
Let U2 = mean sales by type B trainees
Therefore, the null hypothesis (H0) is: U1 - U2 ≤ 0
This implies that type A training does not result in higher mean weekly sales than type B training.
The alternative hypothesis (H1) is: U1 - U2 > 0
This implies that type A training indeed results in higher mean weekly sales than type B training.
