Concept explainers

Power Operation

Power operation is topic of algebra in Math. It is use to represent repeated multiplication. Very big number and very small number can be easily express using power operation. Power operation is useful in many fields. In space engineering, it helps in representing the distance or size of particular heavenly body. In medical field, it is used to represent very small size. In medical field it helps to mention size of bacteria or virus.

Exponents

The exponent or power or index of a variable/number is the number of times that variable/number is multiplied by itself.

Question

Please make sure to do the rounding.

A manager is interested in determining if the population standard deviation has dropped below 118. Based on a sample of n = 17 items selected randomly from the population, conduct the
appropriate hypothesis test at a 0.05 significance level. The sample standard deviation is 91.
Determine the null and alternative hypotheses.
O A. Ho: o2 <118
На: о2 2 118
О В. На о2 2 13,924
HA: o2 < 13,924
ОС. Но о2 %3D118
HA: 02 118
O D. Ho: o2 < 13,924
HA: 02 2 13,924
State the decision rule. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice.
(Round to four decimal places as needed.)
O A. If the test statistic, x > x12 =
reject H, or if the test statistic, x <x-g12 =
reject Ho. Otherwise, do not reject Ho
O B. If the test statistic, x < xÍ-a
reject Ho. Otherwise, do not reject Ho.
O C. If the test statistic, x > xa =
reject Ho. Otherwise, do not reject Ho-
Find the test statistic, x.
(Round to two decimal places as needed.)
Choose the correct conclusion below.
A. Reject Ho. There is insufficient evidence that the population standard deviation is less than 118.
O B. Do not reject Ho. There is insufficient evidence that the population standard deviation is less than 118.
OC. Reject Ho. There is sufficient evidence that the population standard deviation is less than 118.
D. Do not reject Ho. There is sufficient evidence that the population standard deviation is less than 118.
