Answer:
The probability that the value of P will be less than 0.81 is 0.7642.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
The standard deviation of this sampling distribution of sample proportion is:
Given:
<em>n</em> = 100
<em>p</em> = 0.78
Since <em>n</em> = 100 > 30, according to the central limit theorem the sampling distribution of sample proportion follows a Normal distribution.
Compute the value of as follows:
*Use a <em>z</em>-table for the probability.
Thus, the probability that the value of P will be less than 0.81 is 0.7642.
Answer: The slope is -1
Step-by-step explanation:
1. By definition, the equation of the line has the following form:
Where m is the slope and b is the y-intercept.
2. The line given in the problem is .
3. Keeping on mind the form of the equation of the line, you can identify that slope and the y-intercept are:
The answer depends on what is meant by the "fourth term". By the binomial theorem, one answer could be
By symmetry, another could be
