Answer:
The standard error of the proportion is 0.0367.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the standard error is
In this question:
So
The standard error of the proportion is 0.0367.
Answer:
50 trays
3000 cookies
Step-by-step explanation:
We are given the following in the question:
1 cup of brown sugar and cup of granulated sugar makes a tray of 60 cookies.
Total cups of sugar used(brown and granulated) = 1.5 cups
Number of sugar cups used by Lyle each week = 75
We have to find the number of trays made each week.
Thus, 50 trays of cookies are made each week.
Total number of cookies made each week =
Thus, 3000 cookies are made each week.
