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.)

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.

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 =

=

= 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: a and b

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
