Im hoping someone can help do this for me. My data is on left of image, the instructions/example are on the right of image under orange text:http://s29.postimg.org/m0fwf679h/Variables.jpg

Construct a 95%confidenceinterval (Using the following formula: 95% C.I. Equals "mean +/- t*Standard Error" . It also asks for the upper tail and T=, idk how to find that with the t table thing.

You will be using a t-test since you are usingdatafrom a sample and you do not know the population standard deviation. You need to calculate the degrees of freedom (df), which equals sample size minus one (df=n-1).

So basically I need these below answered (I already know the mean and standard error I believe, as shown in the image):

----------------

Mean:

Standard Error:

t:

95% C.I.:

Upper limit:

Lower limit:

"this case we are ???....... "

----------------
