Suppose that true average price of a beer at professional sporting events in the US is $6. You attend 34 events and find an average price of $6.7 and the standard deviation is $0.4. Find the standard error for your sample. Answer to four decimal places.

The standard error for sample is 0.0686 .

Step-by-step explanation:

We know that the formula to find the standard error is given by :-

, where s = standard deviation

n= Sample size

As per given , we have

s=  $0.4  and n= 34

Then , the standard error for sample is given by :-

Hence , the standard error for sample is 0.0686 .

the answer is a) a healthy economy because it results from a steady rise in demand.
