What is different about the normality requirement for a confidence interval estimate of sigma and the normality requirement for

a confidence interval estimate of mu?
The normality requirement for a confidence interval estimate of sigma is ( less strict/ stricter) than the normality requirement for a confidence interval estimate of mu. Departures from normality have a (greater/ lesser) effect on confidence interval estimates of sigma than on confidence interval estimates of mu. That? is, a confidence interval estimate of sigma is (more/less)

robust against a departure from normality than a confidence interval estimate of mu.

Use multiples to write two fractions equivalent to 7/9.
Nitella [24]

Answer:

\frac{14}{18} , \frac{21}{27}

Step-by-step explanation:

To create equivalent fractions multiply the numerator and denominator of the fraction by the same multiples.

Using a multiple of 2, then

\frac{7}{9} = \frac{7(2)}{9(2)} = \frac{14}{18}

Using a multiple of 3, then

\frac{7}{9} = \frac{7(3)}{9(3)} = \frac{21}{27}

7/7q+21= x /5q^2-45 then x=?​
anzhelika [568]

Answer:

x = 5q - 15

Step-by-step explanation:

\frac{7}{7q+21}=\frac{x}{5q^{2}-45}\\\\\frac{7}{7(q+3)}=\frac{x}{5 (q^{2} -9)}\\\\frac{1}{q+3}=\frac{x}{5*(q^{2}-3^{2})}\\\\\frac{1}{q+3}=\frac{x}{5(q+3)(q-3)}\\\\\frac{1}{q+3}*5*(q+3)(q-3)=x\\\\5(q-3)=x\\\\x= 5q-15
