Answer:
15) (1, 1) and (-1, 1)
16) (1, 2) and (-1, 2)
17 (1,1/2) and (-1, 1/2)
18) (1,1/4) and (-1, 1/4)
19) 16 is vertical stretch, 17 and 18 is vertical compressed
Step-by-step explanation:
for qs 15-18 since x is 1 or -1 if you sq 1 or -1 you will always get 1
so y is the "a" value in the equation y=ax²
for qs 19
y=ax²
so if a>1 -- then vertical stretch
when 0<a<1 -- then vertical compressed
Answer:
b. There is sufficient evidence to indicate that exactly 65% of all e-commerce shoppers fail in their attempts to purchase merchandise on-line because Web sites are too complex.
Step-by-step explanation:
Not significant,accept null hypothesis that population proportion = 0.65
When we accept the null hypothesis that P= 0.65
Then only option b is correct which states that there is sufficient evidence to support that population proportion is exactly 0.65 .
1) We obtain a P - value of 0.0522 which is greater than 0.5 indicating that the null hypothesis is not rejected.
The rejection region for this right-tailed test is z > 1.64
2) Test Statistics
z= p`-p0/ sqrt(p0(1-p0)/n)
The z-statistic is computed as follows:
z= 0.75-0.65/ √(0.65*0.35)60
z= 1.624
3) Decision about the null hypothesis
Since it is observed that z = 1.624 is less than z ∝=1.64, it is then the null hypothesis is not rejected.
