The Andrew Jonathan Slottje Company has proposed a new branch in Dallas for next year. The project's returns are as follows:

Year Project return

1994 0.11

1995 0.15

1996 0.13

1997 0.16

1998 0.17

1999 0.19

2000 0.21

2001 0.10

2002 0.09

2003 0.11

Based on this information do the following:

1. Calculate the expected return.
2. Calculate the variance and standard deviation of all the returns.
3. Calculate the coefficient of variation of all the returns.
4. Construct a chart to illustrate the trend in project returns over time.
5. Add a solid line representing the expected return and dotted lines illustrating a 95% confidence interval about the expected return.

6.For 95% confidence is equal to 2.5710. Based on this calculate the upper and lower confidence interval using the standard deviation

of the sample distribution.
