HELP What is the area of a circle with a radius of 13 feet? IT IS NOT 530.93 ft ​

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 1
xeze [42]

The test statistic z  is 2.33, the p-value corresponding to the test statistic z value is 0.0099.

<h3>What is Probability?</h3>

Probability is the measure of the likeliness of happening of an event.

The mean of the data is 15.07 centimeters

The standard deviation of the data is 0.26 centimeters.

n = 75

Significance Level ∝ = 0.01

According to the null and alternative hypothesis

Hₐ : \rm \mu ≤15  vs H₁ : \rm \mu >15

The test statistic z  is given by

\rm Z = \dfrac{(X-\mu)}{\sigma/\sqrt{n}}

Z = ( 15.07 -15)/(0.26/√75)

Z = 2.33

The p-value corresponding to z value is 0.0099

as p-value < significance level, therefore the H₁ : \rm \mu >15 is acceptable.

No, significant evidence is not present to tell that the length of bolts is actually greater than the mean value at a significance level of 0.01.
