Statistics question; please help.
Alex_Xolod [135]

Answer:

Does this sample provide convincing evidence that the machine is working properly?

Yes.

Step-by-step explanation:

<u>Normal distribution test:</u>

$z=\frac{x- \mu }{ \frac{\sigma}{\sqrt{n}} }=\frac{ (x-\mu)\sqrt{n}}{\sigma}  $

Where,

x: \text{ sample mean}

\sigma: \text{ standard deviation}

n: \text{ sample size determination}

\mu: \text{ hypothesized size of the screw}

$z=\frac{(1.476-1.5)\sqrt{200} }{0.203 } $

$z=\frac{(-0.024)10\sqrt{2} }{0.203 } $

z \approx -1.672

Once the significance level was not given, It is usually taken an assumption of a 5% significance level.

Taking the significance level of 5%, which means a confidence level of 95%, we have a z-value of \pm 1.96

Therefore, we <u>fail to reject the null</u>. It means that the hypothesis test is not statistically significant: the average length is not different from 1.5!

Using complete sentences explain which function has the greatest y intercept f(x) = -6x-3 h(x)= 2 cos (x+ pi)-1
V125BC [204]

Answer:

They have the same y-intercept.

Step-by-step explanation:

The y-intercept occurs when x = 0  so for f(x):

y-intercept = f(0) = -6(0) - 3 = -3.

For h(x):

y-intercept = h(0) = 2 cos(0 + pi) - 1

= 2 cos pi - 1

= 2 *-1 - 1 = -3.
