Answer:
The corresponding p - value will be is < 0.00001 which is less than 0.05
Step-by-step explanation:
Suppose p= 0.12 and n= 540 then the standard deviation can be taken out as √p(1-p)/n= √0.12(1-0.12)/540= 0.014
For the probability that the survey will provide a sample proportion within 6.03 of the population proportion
we will find the z statistic
z= p^-p/√p(1-p)/n
But √p(1-p)/n= 0.014 and p^-p= 6.03
Putting the values
z= 6.03/0.014= 430.71
The corresponding p - value will be is < 0.00001 which is less than 0.05
Answer:
P + B = 14130P + 150B = 1920
Step-by-step explanation:
P + B = 14130P + 150B = 1920
P = 14 - B
130(14-B) + 150 = 1920
20B = 100
B = 100/20 = 5
P = 14 - 5 = 9
Answer:
Question unclear.
If the question was about the perimeter of the rectangle, it is calculated as:
= (Length * 2) + (Height * 2)
= (11 * 2) + (6 * 2)
= 22 + 12
= 34 cm
If the question was bout Area, the area is:
= Length * width
= 11 * 6
= 66 cm²
Answer:
2.4 x 10^4 is the answer in Scientific notation.
Step-by-step explanation:
Divide the 22 million by the 900 texts a month to get 24,444 then round to 24,000
