In a random sample of 7 residents of the state of Maine, the mean waste recycled per person per day was 1.4 pounds with a standard deviation of 0.23 pounds. Determine the 95% confidence interval for the mean waste recycled per person per day for the population of Maine. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

The Confidence desired is 0.95 or 95%, then the significance is and , and the critical value in the t distribution with 6 degrees of freedom would be

The 95% confidence interval for the true mean would be between (1.187;1.613)    

Step-by-step explanation:

Information given

represent the sample mean

population mean (variable of interest)

s=0.23 represent the sample standard deviation

n=7 represent the sample size  

Confidence interval

The confidence interval for the mean is given by the following formula:

  (1)

The degrees of freedom are given by

The Confidence desired is 0.95 or 95%, then the significance is and , and the critical value in the t distribution with 6 degrees of freedom would be

Now replacing we got:

The 95% confidence interval for the true mean would be between (1.187;1.613)    

answer: procent 54 wynosi 33,33%

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
