Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 64
Sample mean = 22.3
Sample standard deviation = 8.8
We want to estimate 92% confidence interval.
92% Confidence interval:
Putting the values, we get,
Degree of freedom = n - 1 = 63
Answer:
A is the correct answer.
Step-by-step explanation:
Multiplying something by a fraction is the same as dividing something by the denominator of that fraction, so that makes it simplified to 67 ÷ 6.
67 ÷ 6 is definitely less than 67 but because it is equal to 11.16, it is not between 0 and 1. It is also not greater than 67 or equal to 67, so using the process of elimination, we have found the answer.
Hope this answer helped!
Answer:
In evaluating the solutions, the absolute value should be simplified first to get a positive value.
The definition of absolute value is applied incorrectly. There is no solution.
