Question 263.6 pts

A committee of eight people must choose a president, a vice president, and a secretary. In how many ways can this be done?

Answer 1

Q 13.5)

Sum of the observations = 1 + 1 + 1 + 11 + (-9) = 5

Number of observations = 5

Coming from the population , mean = (sum of observations / number of observations) = 5 /5 = 1

Question 23.5 pts

Here

n = 5

mean = 1

  

  

  

= 40

Question 33.5 pts

Here

n = 5

mean = 1

  

= 50

Question 43.5 pts

Here

Population variance = 40

Population standard deviation = = = 6.3246 6.32

Question 53.5 pts

3, 3 ,7,-2, 0, 1

Mode = most frequent value

The value 3 is repeated two times.

Mode = 3

Question 63.5 pts
