In a random sample of 27 people, the mean commute time to work was 30.4 minutes and the standard deviation was minutes. Assume the population is normally distributed and use a t-distribution to construct a % confidence interval for the population mean mu. What is the margin of error of mu?

The 95% CI is

The margin of error is 2.9 minutes.

Step-by-step explanation:

The question is incomplete:

The sample standard deviation was 7.3 minutes.

Assume the population is normally distributed and use a t-distribution to construct a 95% confidence interval for the population mean mu.

The sample mean is 30.4

The sample standard deviation is 7.3

The sample size is 27.

The degrees of freedom are:

For a 95% CI and df=26, the critical value for t is t=2.056.

The margin of error can be calculated as:

The lower and upper bounds of the 95% CI are:

The 95% CI is then

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.

step-by-step explanation:

hi! i think the answer is 1/2 : )
