WORD PROBLEM NEED DONE ASAP 50 PTS Some members of the track team are practicing running along a marathon course. Their position along the course is given by the variable d, in miles. The variable t represents the amount of time after 9:00 a. m., in hours. Some runners started running before 9:00 a. m.
The position of runner Cheng is given by d=8(t+0.5). The position of runner Antonelli is given by d=4+8t. Which is true?

Runner Antonelli will catch and pass runner Cheng.

Runner Cheng is running at a fixed distance behind runner Antonelli.

Runner Cheng and runner Antonelli are at the same point along the course.

The runners started together, but now runner Antonelli is ahead.
(gives 50 points)

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.
