Question

Calculate descriptive statistics for the variable (Coin) where each of the thirty-five students in the sample flipped a coin 10 times. Round your answers to three decimal places and write the mean and the standard deviation.

Answer 1

Mean = 5; Standard Deviation: 1.5811

Explanation:

Given Data:

number of times coin flipped = n = 10;

probability of each side of coin = p = 0.5;

Here mean is the product of number of times coin flipped and probability of each

m = n*p =10*0.5 = 5

Standard deviation is obtained by taking square root of product of n,p,q

St. Dev=
`√(npq)` =
`√(10*0.5*0.5)` = 1.5811

We have:

Mean = 5 ; Standard Deviation = 1.5811
