The relationship between celcius and fahrenheit of measuring temp is linear. find a linear equation relating c and f if 0c corresponds to 32f and 100c corresponds to 212f. use the equation to find the celcius measure of 70f?
ok guys i'm stuck on this
i have attempted to do it myself and will display below what i have done
i paired it up
(0,32)
(100,212)
(x, 70)
so i tried finding the slop first
212-32/100-0 and got 9/5
then i just set it up as so
y = 9/5x -32
because the y-int is stated up to at (0,32) and "x" in this case represents fahrenheit (f)
but my answer is wrong according to the book
what am i doing wrong?

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.
