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.

<u>Answer:</u>
The second quantity is 1.3333 times the first quantity in the ratio.
<u>Solution:</u>
A ratio is given to us which is 4:3.
What we need to find out is, the second quantity in the ratio is how many times the first quantity in the ratio.
The definition of ratio is, the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
So according to the definition of ratio we get:
So we can say that 4 contains 3, 1.3333 times in it.
So the second quantity is 1.3333 times the first quantity in the ratio.
B. because if you draw another line the parts will be equal.
