Answer:
Avicenna can expect to lose money from offering these policies. In the long run, they should expect to lose ___33__ dollars on each policy sold
Step-by-step explanation:
Given :
The amount the company Avicenna must pay to the shareholder if the person die before 70 years = $ 26,500
The value of each policy = $497
It is given that there is a 2% chance that people will die before 70 years and 98% chance that people will live till the age 70.
The expected policy to be sold= policy nominal + chances of death
                                       = 497 + [98% (no pay) + 2% (pay)]
                                      = 497 + [98%(0) + 2%(-26500)]
(The negative sign shows that money goes out of the company)
                                    = 497 - 2% (26500)
                                   = 497 - 530
                                   =33
Therefore the company loses 33 dollar on each policy sold in the long run.

Answer:
LCL = 59.26 to two decimal places 
Step-by-step explanation:
Here, we want to estimate the LCL of the population mean with 90% confidence 
We proceed as follows;
Given alpha = 0.1, then Z(0.05)=1.645 (from standard normal table), s = 15
Mathematically;
LCL =x_bar -Z*s/√( n)= 62 - (1.645 * 15)/√81
LCL = 62- (24.675)/9 = 59.2583
LCL = 59.26 to two decimal places
