Answer:
a) critical values ≈ -3.182 and 3.182 shows that there is difference in average prices
b) H0 : μd = 0
Ha : μd ≠ 0
Step-by-step explanation:
<u>a) Determine if there is any significant difference in the average prices </u>
using ∝ = 0.05
and μ( advertiser ) - μ ( competitor ) = μd
test statistic ( t ) = -3.011
df = 3
hence the critical values ( two tailed test ) = -3.182 and 3.182. this shows that there is sufficient evidence to show that there is difference in the average prices
<u>b) state the hypothesis</u>
H0 : μd = 0 ( null )
Alternate hypothesis : Ha : μd ≠ 0
Answer:
50 % probability that the hat is blue.
Step-by-step explanation:
3 blue and 3 black = 6 total tickets
3/6 chance of blue and 3/6 change of it being black
3/6 = 1/2 = 0.5 = 50%
1/3 or 5/6
Lets make the fractions into decimals. To make a fraction into decimal you have to divide the numerator by the denominator. The numerator is the top part of a fraction and the denominator is the bottom part of the fraction.

Calculations
1/3
1 ÷ 3 = 0.3333....
5/6
5 ÷ 6 = 0.83333...
0.83333... is greater then 0.3333.....
Therefore 5/6 is greater then 1/3
1/3 is smaller then 5/6
Answer:
81.5
Step-by-step explanation:
I’m assuming you want it in slope intercept form so it’s y=1/6x-2
