Answer:
The mean of the sampling distribution is 0.22 and the standard deviation is 0.0338.
Step-by-step explanation:
Central Limit Theorem:
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation 
In this question, we have that:
a) What are the mean and Standard deviation of the sampling distribution of p-hat
By the Central Limit Theorem,
Mean:
Standard deviation:
The mean of the sampling distribution is 0.22 and the standard deviation is 0.0338.
Use Photomath it’s a good app
Answer:
144 cm²
Step-by-step explanation:
for the triangle sides: 3 x 4 = 12 ((3 x 4/2)x 2)
for the front: 5 x 11 = 55
for the back: 3 x 11 = 33
for the base: 4 x 11 = 44
12 + 55 + 33 + 44 = 144
Do you have a picture of any sort that would go with this ? Or question options ?
Answer:
D
Step-by-step explanation:
If its 1 quarter of a mile in 22.5, then we take <em>s, </em>seconds, times 4 which is 90.
SO we cross out A and B, and we're left with C AND D. Now we check the math on them.
.25/22.5 is 0.01111111 (repeating)
and 22.5/.25 is 90!
