<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 : ≤15 vs H₁ :
>15
The test statistic z is given by
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 : >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.

Answer:
The height of cylinder is: h = 80.07 cm
The diameter of cylinder is: d = 3.5 cm
Step-by-step explanation:
Curved surface area of cylinder = 880 cm^2
Volume of cylinder = 770 cm^3
We need to find its diameter and height.
The formula used are:
If we divide volume by curved surface, we can find radius
So, we get radius r = 1.75
Now, we can find height using curve surface area formula:
So, the height of cylinder is: h=80.07 cm
Now finding diameter using formula:
Putting value of r in above formula:
So, the diameter of cylinder is: d = 3.5 cm
