Chapter 8 assessment 1. suppose a random sample of 100 farm-raised salmon showed an average concentration of mirex (a toxic insecticide) of 0.0761 ppm, with a sample standard deviation of 0.0239 ppm. a. (5 points) use this information to compute a 95% confidence interval for the population mean concentration of mirex in farm-raised salmon. clearly show that you checked to make sure the data meet all necessary conditions for inference. b. (5 points) interpret the meaning of the confidence interval you found in part a in the context of this application. 2. suppose that a simple random sample of 250 u. s. adults showed that 145 of them believe the death penalty is applied fairly. a. (5 points) use this information to compute a 99% confidence interval for the population proportion of u. s. adults who believe the death penalty is applied fairly. clearly show that you checked to make sure the data meet all necessary conditions for inference. b. (5 points) interpret the meaning of the confidence interval you found in part a in the context of this application.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

! < 3

have a splendid day < 3 : )

i belive those are the ones that are under 90 degreese.

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
