Answer:
a) Narrower
b) Narrower
c) Wider
Step-by-step explanation:
We are given the following in the question:
Proportion of coworker who received flu vaccine = 32%
98% confidence interval: (0.231, 0.409)
Confidence interval:
a) Sample size had been 600 instead of 150
If we increase the sample size, thus the standard error of the interval decreases.
Since the standard error decreases, the confidence interval become narrower.
b) Confidence level had been 90% instead of 98%
As the confidence level increases, the confidence interval becomes narrower. This is due to a smaller value of z-statistic at 90% confidence level.
c) Confidence level had been 99% instead of 98%
As the confidence level increases, the width of the confidence interval increases and the confidence interval become wider. This is because of a larger value of z-statistic at 99% confidence interval.
<em><u>The number 0.000000016 is expressed in scientific notation is:</u></em>
<em><u>Solution:</u></em>
Given that,
Charlie learns that a computer processor can perform one command in approximately 0.000000016 nanoseconds
We have to express in scientific notation
<em><u>Step 1:</u></em>
Given number is:
0.000000016
Move the decimal point in 0.000000016 until there is only one non-zero digit to the left of the decimal point
Here,
Move the decimal 8 places to the right to get 1.6
We have moved the decimal to left, therefore, exponent is negative
Thus the given number is expressed in scientific notation
