Researchers wanted to determine weather students taking classes in the morning performed better than students taking classes in the evening on their Probability and Statistics final exam. A random sample of students taking classes in the morning showed the mean final exam score of 178.5 points with the standard deviation of 21..2 points and a random sample of students taking classes in the evening showed the mean final exam score of 168.5 points with the standard deviation of 30.1 points. What is the alternative hypothesis when testing the claim at 5% level of significance

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

answer: 3.26019516

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

really your just stupid if you don't know this
