A doctor is measuring the average height of male students at a large college. The doctor measures the heights, in inches, of a s
RoseWind [281]

Answer:

There is a 95% confidence that the true mean height of all male student at the large college is between the interval (63.5, 74.4).

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for population mean is:

CI=\bar x\pm z_{\alpha/2}\times\frac{\sigma}{\sqrt{n}}

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

The 95% confidence interval for the average height of male students at a large college is, (63.5 inches, 74.4 inches).

The 95% confidence interval for the average height of male students (63.5, 74.4) implies that, there is a 0.95 probability that the true mean height of all male student at the large college is between the interval (63.5, 74.4).

Or, there is a 95% confidence that the true mean height of all male student at the large college is between the interval (63.5, 74.4).

The polynomial 3x2 is a with a degree of .
ZanzabumX [31]

To determine the degree of a polynomial, you look at every term:

  • if the term involves only one variable, the degree of that term is the exponent of the variable
  • if the term involves more than one variable, the degree of that term is the sum of the exponents of the variables.

So, for example, the degree of 7x^{55} is 55, while the degree of xy^2z^4 is 1+2+4 = 7

Finally, the term of the degree of the polynomial is the highest degree among its terms.

So, 3x^2 is a degree 2 polynomial (although it only has one term)

similarly, x^2y + 3xy^2 + 1 is a degree 3 polynomial: the first two terms have degree 3, because they have exponents 2 and 1.
