Last night I ran on a treadmill which tracked my steps per minute. I recorded my steps per minute six times during a 30 minute run. Use the data to calculate a 95% confidence interval for the population mean number of steps.
__________ Calculate the sample size n.
__________ Calculate the sample mean x.
__________ Calculate the sample standard deviation sx.
__________ Calculate the standard error SE of the sample mean x
__________ Calculate tcritical for a confidence level c of 95%
__________ Calculate the margin of error E for the sample mean x.
Write out the 95% confidence interval for the population mean μ steps per minute.
p( __________ < μ < __________ ) = 0.95
__________ My population mean steps per minute while joggling is 150 steps per minute. Could my treadmill steps per minute be 150 based on the above data?
