Step-by-step explanation:
you should copy the question and answers then put it in google or whatever you use so it can spell check, i looked up this question on here and it had only urs so i looked it up through google and mine has a spelling error so yeah now you know for next time
hope this helps :)
Amber plus 2 family members = 3 total people on the plan.
They share the minutes equally so divide the minutes by 3 to find how many she can use:
720 / 3 = 240 minutes per month.
Now divide the monthly minutes by 30 days:
240 / 30 = 8 minutes per day.
Answer:
90

Answer:
95% confidence interval for the percentage of all U.S. public high school students who are obese is [0.110 , 0.190].
Step-by-step explanation:
We are given that 15% of a random sample of 300 U.S. public high school students were obese.
Firstly, the pivotal quantity for 95% confidence interval for the population proportion is given by;
P.Q. =
~ N(0,1)
where,
= sample % of U.S. public high school students who were obese = 15%
n = sample of U.S. public high school students = 300
p = population percentage of all U.S. public high school students
<em>Here for constructing 95% confidence interval we have used One-sample z proportion statistics.</em>
<u></u>
<u>So, 95% confidence interval for the population proportion, p is ;</u>
P(-1.96 < N(0,1) < 1.96) = 0.95 {As the critical value of z at 2.5% level
of significance are -1.96 & 1.96}
P(-1.96 <
< 1.96) = 0.95
P(
<
<
) = 0.95
P(
< p <
) = 0.95
<u>95% confidence interval for p</u> = [
,
]
= [
,
]
= [0.110 , 0.190]
Therefore, 95% confidence interval for the percentage of all U.S. public high school students who are obese is [0.110 , 0.190].
