Evaluate piecewise functions

Mathematics
1 answer:
Mama L [17]2 years ago

6 is neither equal to 0 nor equal to 7, so the last "piece" of h(x) applies. Then

h(6) = 3•6 - 2 = 18 - 2 = 16

An SRS of 27 students at UH gave an average height of 5.6 feet and a standard deviation of .1 feet.Construct a 90% confidence in
Juliette [100K]

Answer:

Option a) [5.567, 5.633]                

Step-by-step explanation:

We are given the following in the question:  

Sample mean, \bar{x} = 5.6 feet

Sample size, n = 27

Alpha, α = 0.10

Sample standard deviation, s = 0 .1 feet

90% Confidence interval:  

\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}  

Putting the values, we get,  

t_{critical}\text{ at degree of freedom 26 and}~\alpha_{0.10} = \pm 1.7056  

5.6 \pm 1.7056(\displaystyle\frac{0.1}{\sqrt{27}} ) = 5.6 \pm 0.0328 = (5.5672 ,5.6328) \approx (5.567,5.633)  

Option a) [5.567, 5.633]
