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 .

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
