Answer:
A. Candice should reject the null hypothesis as the 95% confidence interval does not contain 12 hours
Step-by-step explanation:
Given that:
Average watch hour = 12
sample size = 79
The 95% Confidence interval lies between 7.60 and 11.37.
Thus, since the average watch of students in her school does not lie within the interval between 7.60 and 11.37, Candice should reject the null hypothesis.
Answer:
Omar had the bigger transaction
Step-by-step explanation:
The absolute value of a number is basically the distance between that digit and zero (0) therefore making the absolute value always a positive number. In this instance, the absolute values would be the following
Omar |-15| = 15
Jake |10| = 10
Now that we have both absolute values we can see that Omar had the transaction that involves more money. Exactly $5 more than Jake's transaction.
B
Changing the order does not change the result of the equation
When we raise something to a power, it really justs means we are multiplying it by itself. 3^2 (3 to the power of 2) means that we are mutliplying 3 by itself: 3•3 = 9 or 3^2 = 9 (there are two 3's)
However, when we rasie something to the 0 power, it equals 1. That is because we are multiplying it by itself 0 times. We are not multiplying it by zero, we are effectively doing nothing at all. 3^0 = 1
