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.

A number is first decreased by 40% and then again decreased by 60%. Find the percentage increase or decrease in the whole sum...
dangina [55]

Answer:

It is decreased by 76 percent.

Step-by-step explanation:

The key skills are percentage and multiplication with percentages.

  1. You first have to get a variable. Let's use the letter o as a variable (o For orginial cost).
  2. Then we have to find out how much it is when o is decreased by 40 percent. 100% (or the whole) - 40% is 60%. Therefore, with a 40 percent decrease, It would be 60% of o, or 0.6o.
  3. Then, if it decreases by 60 percent, the final number would be 100% - 60 % or 40% of 0.6o. This means itbwould be 0.4 × 0.6o which is 0.24o
  4. 0.24o means that o is 24 percent of its orginial number, which is 100% - 24% or a 76 percent decrease.
