Step-by-step explanation:

So 4:3 means for 4 girls there are 3 boys. In total, that would be 7.

So, we divide 28 by 7 for 4 meaning 1 in the 4:3 is 4.

And since we are dealing with girls, 4*4=16

To check, 4*3=12 Boys and 16+12=28

If this helped, please feel free to pick this answer as the brainliest! Thank you very much and have a wonderful day!

Sedaia [141]

Answer:

F statistic = 11.3 ;

-1.02

Step-by-step explanation:

____Location1(%C) ____ Location2(%C)

1 ______ 10.40 _________ 10.10

2 _____ 10.20 _________ 10.90

3 ______10.30 _________ 10.20

4 ______10.40 _________ 10.70

5 ______10.20 _________ 10.40

F = larger sample variance / smaller sample variance

Using calculator :

Sample standard deviation (s)

s1² = 0.01

s2² = 0.113

F = s2² / s1²

F = 0.113 / 0.01

F = 11.3

Yes, the two standard deviations for the locations are significantly different at the 95% confidence level.

B.)

Tvalue

x1 = 10.3 ; x2 = 10.46

μ1 = 10.30 ; μ2 = 10.46

(10.30 - 10.46) / sqrt[(0.01/5) + (0.113/5)]

-0.16 / 0.1568438

-1.02
