You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 44 32.8 59.2 31.4 12.7 68.5 84.7 72.5 55.7 Find the 98% confidence interval. Enter your answer as an open-interval (i. e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place). 98% C. I.

And the interval would be:

Step-by-step explanation:

For this problem we have the following dataset given:

44 32.8 59.2 31.4 12.7 68.5 84.7 72.5 55.7

We can find the mean and sample deviation with the following formulas:

And replacing we got:

The confidence interval for the mean is given by:

The degrees of freedom are:

The confidence would be 0.98 and the significance then the critical value would be:

Ad replacing we got:

And the interval would be:

answer is x<
