Answer: Total amount earned is $647.68
Step-by-step explanation:
He worked 3 days at his previous salary of $16/hour. If he works 8 hours per day, then the amount he earned working at the previous salary is
16 × 8 × 3 = $384
This week, Mister Campanello got an increase in his salary of 3%. It means that the amount by which his salary increased is
3/100 × 16 = $0.48
His new salary would be
16 + 0.48 = $16.48
If he worked for 2 days at his new salary, then the amount he earned working at the new salary is
16.48 × 8 × 2 = $263.68
Total amount earned is
384 + 263.68 = $647.68
Answer:
Nominal data are used to label variables without any quantitative value. Common examples include male/female (albeit somewhat outdated), hair color, nationalities, names of people, and so on. In plain English: basically, they're labels (and nominal comes from "name" to help you remember). You have brown hair (or brown eyes).
Answer:
D. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test
Step-by-step explanation:
Hello!
When planning what kind of hypothesis to use, you have to take into account any other studies that were made about that topic so that you can decide the orientation you will give them.
Normally, when there is no other information available to give an orientation to your experiment, the first step to take is to make a two-tailed test, for example, μ₁=μ₂ vs. μ₁≠μ₂, this way you can test whether there is any difference between the two stands. Only after having experimental evidence that there is any difference between the treatments is there any sense into testing which one is better than the other.
I hope you have a SUPER day!
