1) a process that is assumed to be in control with limits of 89 ± 2 had sample averages for the x-bar chart of the following: 87.1, 87, 87.2, 89, 90, 88.5, 89.5, and 88. is the process in control? a) yes. b) no, one or more averages exceeded the limits. c) not enough information to tell. d) no, there is a distinguishable trend. e) no, two or more consecutive points are very near the lower (or upper) limit.

E) No, two or more consecutive points are very near the lower (or upper) limit.

Step-by-step explanation:

A process that is assumed to be in control with limits of 89 ± 2 with following sample averages:

87.1, 87, 87.2, 89, 90, 88.5, 89.5, and 88

We can see that the process is not in control and there are two or more consecutive points that are very near the lower (or upper) limit.

Hence, option E is correct.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
