Answer: 90% confidence interval would be (6.022,6.986).
Step-by-step explanation:
Since we have given that
Number of students = 361
Sample mean = 6.504
Sample standard deviation = 5.584
Standard error of the mean = 0.294
At 90% confidence level,
So, α = 0.01
So, z = 1.64
Margin of error is given by
So, Lower limit would be
Upper limit would be
So, 90% confidence interval would be (6.022,6.986).
Answer:
Answer: 455 / 7
Step-by-step explanation: Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT?
answer choices
455 ÷ 70
455 ÷ 7
45.5 ÷ 7
4.55 ÷ 0.70
The number resulting from the division of one number by another is regarded as quotient. For example, The quotient of 12 divided by 4 is 3.
And so, the first, third and last options on expansion by division all yield the same results in decimals (6.5) as that in the question (4.55 / 0.7 = 6.5) which is an indication that they have the same quotient.
Only the second option does not do so. 455 / 70 = 65
1,080×(1−0.03)^(6)
