A professor believes the students in a statistics class this term are more creative than most other students attending the unive

djverab [1.8K]

Answer:

Correct option: B

Step-by-step explanation:

The professor can perform a One-mean t-test to determine whether the average score of the students in his class is more than the average score of all the students attending university.

A t-test will be used instead of the z-test because the population standard deviation is not provided instead it is estimated by the sample standard deviation.

The hypothesis for this test can be defined as follows:

H₀: The average score of the students in his class is not more then the entire university, i.e. μ ≤ 35.

Hₐ: The average score of the students in his class is more then the entire university, i.e. μ > 35.

Given:

$\bar x=40\\SE_{\bar x}=1.63$

The test statistic is:

$t=\frac{\bar x-\mu}{SE_{\bar x}}=\frac{40-35}{1.63}=3.0674\approx3.07$

Thus, the correct option is (B).

The potential energy, P, in a spring is represented using the formula P = P equals StartFraction one-half EndFraction k x square

Anastaziya [24]

Answer:

$k=\frac{2P}{x^{2}}$

Step-by-step explanation:

The question is

Which equation should she use?

we have the formula

$P=\frac{1}{2}kx^{2}$

Solve for k

That means ----> isolate the variable k

Multiply by 2 both sides

$2P=kx^{2}$

Divide by x^2 both sides

$\frac{2P}{x^{2}}=k$

Rewrite

$k=\frac{2P}{x^{2}}$

What whole number come before 105

ZanzabumX [31]

The whole number that comes before 105 is 104.

However, it is not the only whole number that comes before 105.

Whole numbers are identified as natural number and zero (0). Meaning the whole number starts with 0 then followed by 1,2,3,4.... so on. Whole numbers are positive numbers without remainders nor fractions.

Whole number that come before 105 range from 0 to 104.

Natural numbers are also called counting numbers; They start with 1. Zero is not a natural number because it cannot be counted.

Integers are numbers which can be positive or negative and it includes zero.
