Answer:
Confidence Interval =-3.4085 ,+0.7915
Step-by-step explanation:
The confidence interval can be determined by
(x1`- x2`) ± 1.955 √s1²/n1 + s2²/n2
The mean and the standard deviations can be calculated using the calculator.
The mean x1`= ∑x/ n= 2+ 2+ 2+ 5+ 5+ 5+ 1+2+ 3+ 5/10
= 32/10= 3.2
Standard deviation = s1`= 1.536
The mean x2`= ∑x/ n= 5 +4 +5+ 7+ 4+ 7+ 5+ 4+ 4+ 8/10
= 53/10= 5.3
Standard Deviation = s2= 1.4177=1.42
Putting the values
(x1`- x2`) ± 1.955 √s1²/n1 + s2²/n2
(3.2-5.3 ) ± 1.955 √1.54²/10 +1.42²/10
-2.1 ± 1.955 √ 2.37/10 +2.11/10
-2.1 ± 1.3085
-3.4085 ,+0.7915
Answer:
the first option
Step-by-step explanation:
it is directly there in the problem description.
f(x) = 1.8x - 10
g(x) = -4
so, for f(x)=g(x) that automatically means
1.8x - 10 = -4
1.8x = 6
x = 6/1.8 = (6/1) / (18/10) = 10×6 / 18×1 = 60/18 = 10/3
