A 98% confidence interval for the mean of a population is to be constructed and must be accurate to within 0.3 unit. A preliminary sample standard deviation is 1.7. The smallest sample size n that provides the desired accuracy is

And the value for n rounded up would be n = 174

Step-by-step explanation:

We have the following info given:

previous estimation for the deviation

the margin of error desired

represent the confidence

The Margin of error is given by:

If we solve for the value of n we got:

For this problem we know that the confidence is 98% so then the significance level would be and the critical value would be:

And replacing we got:

And the value for n rounded up would be n = 174

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.
