Question

I need answers for question 3 and 4. I believe I'm correct with question 1 and 2 but not sure which could make question 3 and 4 incorrect.

1. 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 type the mean and the standard deviation in the grey area below.

2. Mean: 4.885 Standard deviation: 1.490

3. List the probability value for each possibility in the binomial experiment calculated at the beginning of this lab, which was calculated with the probability of a success being ½. (Complete sentence not necessary; round your answers to three decimal places)

P(x=0)			P(x=6)
P(x=1)			P(x=7)
P(x=2)			P(x=8)
P(x=3)			P(x=9)
P(x=4)			P(x=10)
P(x=5)

4. Give the probability for the following based on the calculations in question 3 above, with the probability of a success being ½. (Complete sentence not necessary; round your answers to three decimal places)

P(x≥2)			P(x<0)
P(x>2)			P(x≤5)
P(5<x ≤7)			P(x<5 or x≥7)

Answer 1

Solution:

List the probability value for each possibility in the binomial experiment calculated at the beginning of this lab, which was calculated with the probability of success being ½. (Complete sentence not necessary; round your answers to three decimal places)

Answer: We have to use the binomial probability distribution to find the given probabilities.

Here we have:
