Answer:
Part A
The probability of the treatment groups mean being greater than the control group mean by 8points or more = (26+8+2)/1000 = 0.036
Part B
Yes, the result is statistically significant because the probability of the difference being 8point or more is less than 5% significant level
Part C
The answers is 0.036 means that there is a very little chance of obtaining difference of 8points or more by random chance. So, if the difference between treatment group mean and control group mean is at least 8 , then the result is significant which means protein shaken is actually helpful in speeding up the weight-10 process
