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
I don't see a question here, but I think your asking how many sixth graders will attend. The answer is 24.
My method is on a) you would just subtract 12 and 7 which is 5. You can do the rest and then when you get all the answers put them from smallest to largest
Answer:
x = 23
Step-by-step explanation:
2x -3 + 47 = 90
2x = 46
x = 23
