Answer:
(7,-3)
Step-by-step explanation:
y = -3
substitute in the first equation
3x - y^2 = 12
3x - (-3)^2 = 12
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 7
coordinates of intersection (7,-3)
Answer:
a. We do not have enough evidence to conclude that the two means differ.
b. There is no difference in the population means.
Step-by-step explanation:
a) Results of the test:
Having p - value to be very high, we have strong evidence of not rejecting H o and hence,
We do not have enough evidence to conclude that the two means differ.
b) For a one tailed test,
p - value = 0.115/2 = 0.0575
Interpretation: p - value is the probability of getting the difference as small as obtained in the sample, given that the null hypothesis is true i.e. there is no difference in the population means.
