Question

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. Name Score Julia 650 Andrew 550 Jason 380 Cathy 720 Jessica 710 Robert 550 The table gives the scores of 6 students from a class of 25 in a competitive exam. The point estimate of the mean score for the students is . (Round off your answer to the nearest tenth.)

Answer 1

Answer:

Mean score for the students = 593.3

Step-by-step explanation:

Name    Score

Julia      650

Andrew 550

Jason    380

Cathy     720

Jessica   710

Robert    550

1) Mean Score = $\frac{Sum of the scores}{Total number of students}$

= $\frac{650+550+380+720+710+550}{6}$

= 593.33

2) Upon rounding off to the nearest tenth, we get

Mean Score = 593.3 (since the hundredth digit is lesser than 5, the tenth digit is not increased)

Answer 2

Answer:

593.3

Step-by-step explanation:

Assuming random sample, assuming "point estimate of mean score" means "estimate of mean score in points",

(650+550+380+720+710+550)/6 is 593.3

Sample size 6 population size 25 is irrelevant except to note estimate might not be very good.
