7 because it isnt 6 so its 7
Answer:
The mean is 0.32 and the standard deviation is 0.0122.
Step-by-step explanation:
Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.
Of the respondents, 48% said they put their shirt on first.
32% of all adults actually put their shirt on first
i.e. sample proportion is 48% while population proportion is 32%
Hence sampling distribution follows a distribution with mean = population proportion p
Hence here mean = 0.32
Std deviation of sampling distribution = ![\sqrt{\frac{pq}{n} } =\sqrt{\frac{0.32(0.68)}{1457} } \\=0.0122](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bpq%7D%7Bn%7D%20%7D%20%3D%5Csqrt%7B%5Cfrac%7B0.32%280.68%29%7D%7B1457%7D%20%7D%20%5C%5C%3D0.0122)
Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.
is right
Answer:
C. 4.3
Step-by-step explanation:
Given that
n = 17
P = 1/4
Using binomial
Mean = np
Mean = 17 × (1/4)
= 17 × .25
= 4.25
Approximately = 4.3
Answer:
2 16/36
Step-by-step explanation:
see how many times 36 goes into 88 with out going over 36 * 2 = 72 than go 88 - 72 to get the remainder of 16
Answer:
Step-by-step explanation:
use formula
A(x,y)=A'(-x,y)
(-2,-3)=(2,-3)
