Review the graph of function h(x). What is lim h(x), if it exists?

erastova [34]

Answer:

Step-by-step explanation:

because you have to look at what both sides of the graph is doing as it approaches 2.

from the left, we can see the the graph is going down All the way to 0 at x=2.

and from the right side, the graph is going up to 0 at x=2.

therefore the graph is approaching 0.

Lifetimes of AAA batteries are approximately normally distributed. A manufacturer wants to estimate the standard deviation of th

AURORKA [14]

Answer:

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.

(8.889, 11.7106)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 23

Mean of the sample x⁻ = 10.3

Standard deviation of the sample (s) = 2.4

Level of significance = 0.05

Degrees of freedom = n-1 = 23-1 =22

Step(ii):-

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.

$(x^{-} - t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} } , x^{-} +t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} } )$

$(10.3 - t_{\frac{0.05}{2} } \frac{2.4}{\sqrt{23} } , 10.3 +t_{\frac{0.05}{2} } \frac{2.4}{\sqrt{23} } )$

(10.3 - 2.8188 (0.50043) , 10.3 + 2.8188(0.50043)

(10.3-1.4106 , 10.3+1.4106)

(8.889, 11.7106)

final answer:-

95% confidence interval for the population standard deviation of the lifetimes of the batteries produced by the manufacturer.
