In a study conducted by the u. s. department of health and human services, a sample of 546 boys aged 6–11 was weighed, and it was determined that 91 of them were overweight. a sample of 508 girls aged 6–11 was also weighed, and 74 of them were overweight. can you conclude that the proportion of boys who are overweight differs from the proportion of girls who are overweight? find the p-value and state a conclusion. round the answer to four decimal places.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
