A+B: the matrix with same dimension a A and B, the element in row i and column j is: Aij+Bij
Same for A-B, but with Aij-Bij
X^2 -13x +30 = 0
x*x - 15x +2x +15*2 = 0
x(x -15) -2(x -15) = 0
(x -2)(x -15) = 0
x -2 = 0
x =2
x -15 =0
x = 15
-3
-3 2/8 is the same as -3 1/4
-3 1/4 + 1/4 = -3
Answer:
a) Right-tailed test
b) 0.006569
c) We reject .
Step-by-step explanation:
We are given the following information in the question:
We are testing the claim that p > 0.7
Alpha, α = 0.05
a) We have to identify type of test.
Since we test for claim p > 0.7, it is a one-tailed(right) test.
b) The p-value can be calculated with the help of standard normal table.
C) Since the p-value is less than the significance level, we fail to accept the null hypothesis and reject the null hypothesis.
Thus, we reject .
