Serhud [2]

Answer:

The value of the test statistic is t = 1.97

Step-by-step explanation:

The null hypothesis is:

H_{0} = 250

The alternate hypotesis is:

H_{1} \neq 250

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the null hypothesis value, \sigma is the standard deviation and n is the size of the sample.

In this problem:

X = 251.6, \mu = 250, \sigma = 5.4, n = 44

So

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{251.6 - 250}{\frac{5.4}{\sqrt{44}}}

t = 1.97

The value of the test statistic is t = 1.97

Find f^-1(x) and it’s domain.
Mrac [35]

Answer: A

Step-by-step explanation:

Letting f(y)=x,

x=\sqrt{y}-5\\\\x+5=\sqrt{y}\\\\y=(x+5)^{2}

Also, the domain of an inverse is the same as the range of the original function, so the range is x \geq 0
