Consider two bonds, HI and LI. The HI bond has a 10% coupon rate and the
LI bond has a 5% coupon rate. Both bonds pay interest annually and are priced to yield
10%. Suppose the following interest scenarios are possible at the point in time when both
bonds have five years remaining to maturity:
A vendor claims that the variance for measurement of tiles that his factory produce were 13 square feet. A sample of nine tiles was measured in square feet and the results of the tiles produced were recorded as below: 204.5 206.3 202.4 207.8 203.1 206.2 203.8 206.6 205.8 (Assuming the sample comes from a normal population) i) Calculate the point estimate of the population mean. (2 marks) ii) Compute the variance and standard deviation. (3 marks) iii) Determine the estimate of 95% confidence interval for the population mean of the tiles.
A bottling company uses a filling machine to fill plastic bottles with a popular cola. The bottle are supposed to contain 300 millilimeters. In fact, the contents vary according to a normal distribution with mean =298 ml and standard deviation = 3ml.

b. What is the probability that the mean contents of the bottles in a six-pack is less than 295 ml?
