Mrs. Smith wanted to determine if the 7th grade students who received a passing grade spent more time studying than those students who failed. The dot plots below show the number of minutes spent studying for a test by randomly selecting 29 students’ names from a container of her 7th grade students who passed and students who failed.

What inference can be made about the population based on this data?

Mrs. Smith’s average 7th grade students who passed studies about 25 minutes more than the average students who failed.

Mrs. Smith’s average 7th grade students who passed or failed both study for 30 minutes.

Mrs. Smith’s average 7th grade students who failed did not have time to study after completing their chores.

Mrs. Smith’s average 7th grade students who failed studies 35 minutes less than the average 7th grade students who passed.

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.
