Answer:
The correct order is :
1. Determine the null and alternative hypothesis.
2. Select a sample and compute the z - score for the sample mean.
3. Determine the probability at which you will conclude that the sample outcome is very unlikely.
4. Make a decision about the unknown population.
Step-by-step explanation:
The correct order of the steps of a hypothesis test is given following
1. Determine the null and alternative hypothesis.
2. Select a sample and compute the z - score for the sample mean.
3. Determine the probability at which you will conclude that the sample outcome is very unlikely.
4. Make a decision about the unknown population.
These steps are performed in the given sequence to test a hypothesis.
Answer:
German
Step-by-step explanation:
Given :
Number of people who spoke French as first language in 2000 = 7.7 * 10^7 ; in standard form ;
7.7 * 10^7 = 7.7 * (10 * 10* 10 * 10* 10* 10 * 10) = 77,000,000 = 77 million
Number of people who spoke German as first language in 2000 = 1 * 10^8 ; in standard form ;
1 * 10^8 = 1 * (10 * 10* 10 * 10* 10* 10 * 10 * 10) = 100,000,000 = 100 million
German had more speakers
Cosθ = 15/17
Step-by-step explanation:
Sinθ = 8/17
We know that,
Sin^2 θ + cos^2 θ =1
64/289 + cos^2 θ =1
1 - 64/289 = cos^2 θ
225/289 = cos^2 θ
Cos θ = √225/289
Cos θ = 15/17
The total amount of money Christina spent on streaming music service in a year is $36
<h3>How to find the total cost</h3>
- One time payment = $18
- Cost of each song = $1.20
- Number of songs = 15
Total yearly cost = One time payment + Cost of each song(Number of songs)
= 18 + 1.20(15)
= 18 + 18
= $36
Therefore, the total amount of money Christina spent on streaming music service in a year is $36
