Question

Simplified version:

Calculate descriptive statistics for the variable (Coin) where each of the "thirty-five" students in the sample flipped a coin 10 times. Find the mean and the standard deviation.

Note: This is a Binomial Distribution problem, NOT a Binomial Experiment where the occurrences are recorded or provided, nor are individual trials needed unless you are calculating the success for each coin toss which is not what is being asked for in the question. Just the Mean and Standard Deviation...

We know that:

   - A coin has only 2 sides, so p=0.50 obviously…

   - The Sample Space is 10 coin flips, so we assume n=10, however, what about the 35 students…?

   - mean=n*p

   - where n = number of trials and p=probability of success

   - Standard Deviation = √npq

   - Where q=1-p (probability of failure)

   - "What is the value of n and why?"

Unedited version:

Using the data file from your instructor (same one you used for the Week 2 lab), 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 gray area below.
