Delvig [45]

Answer:

18.0167≤x≤21.9833

Step-by-step explanation:

Given the following

sample size n = 10

standard deviation s = 3.2

Sample mean = 20

z-score at 95% = 1.96

Confidence Interval = x ± z×s/√n

Confidence Interval = 20 ± 1.96×3.2/√10

Confidence Interval = 20 ± (1.96×3.2/3.16)

Confidence Interval = 20 ± (1.96×1.0119)

Confidence Interval = 20 ±  1.9833

CI = {20-1.9833, 20+1.9833}

CI = {18.0167, 21.9833}

Hence the required confidence interval is 18.0167≤x≤21.9833

bazaltina [42]

Answer:

1st answer is in the pic

2nd answer is that there are

1650 childs and 550 adults

Step-by-step explanation: the picture

If you want the 1st answer in words, it is here

Correct result:

a =  100

c =  800

t =  300

Solution:

6a + 5t + 4c = 5300

a + t + c = 1200

(8/3)t = c

6•a + 5•t + 4•c = 5300

a + t + c = 1200

(8/3)•t = c

6a+4c+5t = 5300

a+c+t = 1200

3c-8t = 0

a = 100

c = 800

t = 300
