Answer:
Step-by-step explanation:
Given that a data set includes 109 body temperatures of healthy adult humans for which sample mean =98.2°F and s equals 0.62 degrees
Std error of mean = 
df = 108
Critical value for 99% t =2.581
Margin of error = 2.581*std error = 0.1533
99% confidence interval = Mean ±0.1533
=
a) Since the confidence interval does not contain 98.6 degrees we reject the null hypothesis that mean = 98.6 degrees
b) confidence interval for population mean = 98.6±0.1533
=
Answer:
The answer would be (2,2) or B
Step-by-step explanation:
Kingsley must multiply the measure in centimeters by 1 / 2.54 to get a unit conversion equation in inches.
<h3>How to derive a unit conversion formula?</h3>
Kingsley knows the conversion rate between inches and centimeters and wants to derive a formula. Both the inch and the centimeter are length units and we can represent it by the following ratio:
y / x = 2.54 (1)
Where:
- y - Length, in centimeters.
- x - Length, in inches
Then, we clear the variable x in (1) to find the unit conversion formula:
x = y / 2.54 (2)
Kingsley must multiply the measure in centimeters by 1 / 2.54 to get a unit conversion equation in inches.
