The following scatter plot represents the number of vacation days employees reported based on the number of years employed at their company. A scatter plot with the x-axis labeled Years Employed and y-axis labeled Vacation Days. It contains 10 points that are modeled by f of x equals 2 x plus 2 point 8. The points generally go up quickly to the right.

The data is modeled by the function f(x)=2x+2.8.
What does 2.8 represent in the function?

When an employee is employed for 2.8 years, they can expect to have 0 vacation days.
When an employee starts their job, they can expect to have 2.8 vacation days.
For each year of employment, employees can expect to get 2.8 additional vacation days.
For every 2.8 years of employment, employees can expect to get 1 additional vacation day.

Listed below are time intervals (min) between eruptions of a geyser. assume that the "recent" times are within the past few years, the "past" times are from around 20 years ago, and that the two samples are independent simple random samples selected from normally distributed populations. do not assume that the population standard deviations are equal. does it appear that the mean time interval has changed? is the conclusion affected by whether the significance level is 0.10 or 0.01? recent 78 90 90 79 57 101 62 87 71 87 81 84 57 80 74 103 62 past 88 89 93 94 65 85 85 92 87 91 89 91 follow the steps of hypothesis testing, including identifying the alternative and null hypothesis, calculating the test statistic, finding the p-value, and making a conclusions about the null hypothesis and a final conclusion that addresses the original claim. use a significance level of 0.10. is the conclusion affected by whether the significance level is 0.10 or 0.01? answer choices below: a) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.01 but is not rejected when the significance level is 0.10. b) no, the conclusion is not affected by the significance level because h0 is not rejected regardless of whether a significance level of 0.10 or 0.01 is used. c) yes, the conclusion is affected by the significance level because h0 is rejected when the significance level is 0.10 but is not rejected when the significance level is 0.01. d) no, the conclusion is not affected by the significance level because h0 is rejected regardless of whether a significance level of 0.10 or 0.01 is used.
