A climate researcher knows that it has previously been the case that the mean temperature in his city has been 75.1 °F. He suspects that this may no longer be the case and that the mean temperature may now have changed, and he suspects that is has risen in recent times. He collects sample data with the aim of conducting a hypothesis test to examine his suspicions. He will use a level of significance of 0.01 for the test. Select the correct null and alternate hypotheses for this test:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
