The​ _____ _____, denoted ModifyingAbove p with caretp​, is given by the formula ModifyingAbove p with caretpequals=​_____, wher
Vlada [557]

Answer:

The​ <u>sample proportion</u>, denoted by  ^p​, is given by the formula ^p=​ \frac{x}{n}, where x is the number of individuals with a specified characteristic in a sample of n individuals.

Step-by-step explanation:

Sample proportion is used to determine sample mean, sample standard error and test the hypotheses about the population.

<em>sample mean</em> can be stated as p and <em>sample standard error</em> can be found using the equation\sqrt{\frac{p*(1-p)}{n} } where

  • n is the sample size
  • p is the sample proportion

And if n×p×(1-p)≥10, then sample is assumed large enough to assume normal distribution and apply statistical test.

Subtract 16 to both sides making it equal to 0.

x^2 - 9x - 8 = 0

Using Quadratic Formula to Solve for x.
