Answer:
a
The 95% confidence interval is
Generally the interval above can interpreted as
There is 95% confidence that the true proportion of Wal-Mart stores that have more than 2 items priced inaccurately per 100 items scanned lie within the interval
b
Generally 99% is outside the interval obtained in a above then the claim of Wal-mart is not believable
c
Step-by-step explanation:
From the question we are told that
The sample size is n = 60
The number of stores that had more than 2 items price incorrectly is k = 52
Generally the sample proportion is mathematically represented as
=>
=>
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the margin of error is mathematically represented as

Answer:
m = 2
Step-by-step explanation:
Slope Formula:
Simply plug our coordinates into the slope formula and solve for <em>m</em>:
m = (5 - 3)/(4 - 3)
m = 2/1
m = 2
Answer:
$638.25
Step-by-step explanation:
The interest is 5.5% yearly and it is simple interest.
Now, if we consider a deposit of $575 into the bank account that earned 5.5% simple interest each year, then after 2 and half years James will get interest only for 2 years as the 3rd year's interest will be added after the 3rd year.
Therefore, if no money was deposited into or withdrawn from the account, then after 2.5 years the sum will be
dollars. (Answer)
