140,000,,, 50,000 is estimated
Answer:
A.The probability that exactly six of Nate's dates are women who prefer surgeons is 0.183.
B. The probability that at least 10 of Nate's dates are women who prefer surgeons is 0.0713.
C. The expected value of X is 6.75, and the standard deviation of X is 2.17.
Step-by-step explanation:
The appropiate distribution to us in this model is the binomial distribution, as there is a sample size of n=25 "trials" with probability p=0.25 of success.
With these parameters, the probability that exactly k dates are women who prefer surgeons can be calculated as:
A. P(x=6)
B. P(x≥10)
C. The expected value (mean) and standard deviation of this binomial distribution can be calculated as:
Answer: 20
Step-by-step explanation:
If the number is greater then 5 ( ex: 9, 8, 7) it will be rounded to the nearest whole number which in this equation would be 20
the answer is true i looked it up
The mean absolutely deviation is 315.8
To get the mean you add all the numbers together to get the sum (4737) and devide by how many numbers you had (15)
