A company would like to advertise that their new fishing line has an average breaking strength greater than 15 kilograms. The lines breaking strength is known to vary in the population on average 2.8 kilograms. To test the breaking strength of their new product the company takes a random sample of 50 lines, the average strength measure is 16.1 kilograms. What type of procedure should they use to test whether there evidence that the average strength of the new fishing line is greater than 15 kilogram.

Answers

Answer 1

Answer:

A right-tailed test should be used to test whether there evidence that the average strength of the new fishing line is greater than 15 kilogram.

Step-by-step explanation:

Type of procedure:

We want to test if the breaking strength is greater than a value, which means that the type of procedure used to solve this question is a right-tailed test, which is when we find the probability of having a mean higher than the sample mean found.

Other types of procedures:

Not related to this question speficially, but to similar problems.

To test if a measure is less than another measure, the procedure used is a left-tailed test.

To test if a measure is different from another measure, the procedure used is a two-tailed test.

Answer:

  c.  Both m(x) and p(x) have the same output value at x = 7.

Step-by-step explanation:

For input value x, m(x) is the output value.

m(7) is the output value of the function m(x) when x=7.

p(7) is the output value of the function p(x) when x=7.

The statement m(x) = p(x) for x=7 is a statement that the output values are the same at x=7.

Step-by-step explanation:

Given 9/16×4/12+9/16×-5/9​

Using the PEMDAS rule;

Multiplication first

(9/16×4/12)+(9/16×-5/9​)

= 3/4 * 1/4 + -5/16

= 3/16 - 5/16

= (3-5)/16

= -2/16

Why 117+3 = 5! is correct

Answers

Answer:

5!= 5×4×3×2×1

117+3=120

5×4×3×2×1= 120

therefore 117+3=5! is correct

The statement 117+3 = 5! is correct because;

The left hand side and right hand side give the same solution of 120.

We want to find out why 117 + 3 = 5! is correct.

Let us first find the left hand side of the equation;

117 + 3 = 120

Now, for the right hand side, 5! simply means 5 factorial.

Factorial of a number is a term used in maths to denote the product of all

positive integers less than or equal to that number. For example; n!. That is

factorial and it means the product of all positive integers below n.

Let's apply the concept of factorial to 5!.

All positive integers less than or equal to 5 are; 5, 4 , 3, 2, 1

Thus; 5! = 5 × 4 × 3 × 2 × 1 = 120

This 5! = 120 and it is the same as 117 + 3 = 120. Thus the given statement in the question is true.

Find the probability that the mean life of a random sample of such bulbs will be

Answers

Answer:

Hi your question is incomplete attached below is the complete question

answer : p ( X < 725 )  = 0.0116

Step-by-step explanation:

Given data:

Average life of bulbs (μ  ) = 750 hours

standard deviation (б ) = 55 hours

n ( sample size ) = 25

X = 725  

Probability that the mean life of a random sample of 25 bulbs will be less than725 hours

p ( X < 725 ) = p (( X - μ )/ б √n  <  725 - 750 / 55√25 )

                     = P ( Z > - 2.27 )

Hence P ( X < 725 ) = 0.0116  ( using Z-table )
