Answer:
Since the calculated value of t= 2.249 does not falls in the rejection region we therefore accept the null hypothesis at 5 % significance level . On the basis of this we conclude that the bonus plan has not increased sales significantly.
Step-by-step explanation:
The null and alternative hypotheses as
H0: μd=0 Ha: μd≠0
Significance level is set at ∝= 0.05
n= 6
degrees of freedom = df = 6-1 = 5
The critical region is t ( base alpha by 2 with df=5) ≥ ± 2.571
The test statistic under H0 is
t = d/ sd/ √n
Which has t distribution with n-1 degrees of freedom
Sales Difference
Person After Before d = after - before d²
1 94 90 4 16
2 82 84 -2 4
3 90 84 6 36
4 76 70 6 36
5 79 80 -1 1
<u>6 85 80 5 25 </u>
∑ 18 118
d`= ∑d/n= 18/6= 3
sd²= 1/6( 118- 18²/6) = 1/6 ( 118 - 54) = 10.67
sd= 3.266
t= 3/ 3.266/ √6
t= 2.249
Since the calculated value of t= 2.249 does not falls in the rejection region we therefore accept the null hypothesis at 5 % significance level . On the basis of this we conclude that the bonus plan has not increased sales significantly.
Answer:
True, a strict inequality would be graphed with a dashed line
Answer:
All real numbers greater than or equal to -1 and less than or equal to 2
Step-by-step explanation:
Let
A_1 ------> the area of rectangle
A_2 ----> the area of triangle
we know that
<em>Find out the area of rectangle</em>
<em>Find out the area of triangle</em>
substitute
Simplify
<em>First case (positive value)</em>
<em>Second case (negative value)</em>
Multiply by -1 both sides
therefore
The solution for x is the interval -----> [-1,2]
All real numbers greater than or equal to -1 and less than or equal to 2
A=pw-31.20=52p- which equals 0.6 or 60% but then you subtract that from 100% to get 40% discount
