Answer:
Step-by-step explanation:
We first begin by finding how much the total expenses will be;
£6 per person per night = £6 * 2persons * 10nights = £120
They also need to pay for 8 nights out of 10 for the ground surface of the tent pitch. Since their tent is 9.66m², it's less than 10m² so they get to pay £15 * 8 = £120. We calculate for only one tent because they're sharing.
Their total expenses are £120 + £120 = £240.
Now let's look at their savings;
£13 * 2 persons * 9 weeks = £234
They will not have enough money for their holiday because they are £6 short of the £240 funds required.
Answer:
The margin of error for her confdence interval is of 0.3757.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 18 - 1 = 17
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level of
. So we have T = 2.8982
The margin of error is:

In which s is the standard deviation of the sample and n is the size of the sample.
Standard deviation of 0.55 meters.
This means that 
What is the margin of error for her 99% confidence interval?



The margin of error for her confdence interval is of 0.3757.
After Doing the math the answer is 72 Inches or 6 feet
