Lara is calculating the standard deviation of a data set that has 8 values. She determines that the sum of the squared deviations is 184.

What is the standard deviation of the data set?

Round the answer to the nearest tenth.

Enter your answer in the box.

4.8 to the nearest tenth.

Step-by-step explanation:

The variance = 184 / 8 = 23

The standard deviation = the square root of the variance

=  √23

= 4.796.

-4

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
