You want to know about the dining habits of college students in the US. Since you do not have resources to survey all college students in the nation, you take a random sample of 1501. You learn that, on average, they eat out 4 times per week. Also, these sample data are generally distributed about the average of 4 times, by 1.5 times per week. 1. What is the average times per week that college students across the nation eat out
Answer:
the average times per week that college students across the nation eat out lies within these 95% confidence interval
[tex] 3.938 < \mu < 4.062 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 1501
The sample mean is [tex]\= x = 4[/tex]
The standard deviation is [tex]\sigma = 1.5[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.96 * \frac{1.5 }{\sqrt{1501} }[/tex]
=> [tex]E = 0.06196 [/tex]
Generally the estimate for average times per week that college students across the nation eat out at a 95% confidence is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
[tex]4 -0.06196 < \mu < 4 + 0.06196[/tex]
=> [tex] 3.938 < \mu < 4.062 [/tex]
Hence the true average times per week that college students across the nation eat out lies within this interval

Tori had a $300 unpaid balance after last month's payment on her account. Her annual percentage rate is 21%. The minimum payment due is $25. How much of that is interest for one
month on the unpaid balance?
Answer:
After the passage of a month, the interest that Tori must pay will be $ 4.81.
Step-by-step explanation:
Given that Tori has an unpaid balance of $ 300 on her credit card, and that said credit card has an annual interest of 21% on the unpaid balances, considering that the minimum payment is $ 25, to determine how much she should pay after a month of After your debt, it is necessary to perform the following calculation:
12 = 21
1 = X
21/12 = X
1.75 = X
((300 - 25) x 1.75 / 100) + 300 = X
4.81 + 300 = X
304.81 = X
Thus, after the passage of a month, the finance charge that Tori must pay will be $ 4.81.

Answer:
the answer is D. 38.15
Step-by-step explanation:
the lunch meat is 5.50 for 5lbs. She only needs 2 1/2 lbs so you would just divide 5.50 by 2 (because 2 1/2 is half of 5). for the soft drinks, it is 9.99 for 3 so each one 3.33 (divide 9.99 by 3). When you add two more to get five cases in total, you get 16.65 (because 9.99 plus 3.33 plus 3.33 = 16.65). the lunch meat is 4.25 each and you need 3 so you just multiply 4.25 by 3. the snack mix bags are 2 for 1.50 each. that means that two is 3.00. you need four so you just do 3.00+3.00 which equals 6. when you add these totals together, you get 38.15
At a coffee shop, the first 100 customers' orders were as follows. What is the probability that a customer ordered a hot drink given that he or she ordered a large? PLEASE HELP
Answer:
22%
Step-by-step explanation:
5+ 48 +22 +8 +12 +5 = 100
so hot/ large
22%
The probability that a customer ordering a hot drink given that he or she ordered a large will be 22%.
What is Probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
From the table, we can see that the hot and large coffee customers are 22 in number.
The total number of customers is 100.
Probability = 22 / 100 = 22%
Therefore the probability that a customer ordering a hot drink given that he or she ordered a large will be 22%.
