If u add them all up and multiple by two in total he walks 43 blocks
Answer:
15
Step-by-step explanation:
the answer should be 15 because, if one cup is 120 calories or 8 fluid ounces is 120 calories, divide 120 by 8 so you can find how many calories one fluid ounce is.
26 % ------------------------ $45.50
100 % ----------------------- $x
--------------------------------------------
26 : 100 = 45.50 : x
26 x = 4,550
x = 4,550 : 26
x = $175
Answer:
It made $175 in total sales.
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].
