clients have been complaining that the machine supplies less than 500ml II) The manager wants to make sure that the amount of cola does not exceed 500ml III) The manager wants to minimize customer complaint and at the same time does not want any overflow. He takes up 36 cups of sample and finds the sample mean to be 499 ml. The specification of the machine says that generally the standard deviation is 1 ml. He does a hypothesis testing at 10% level of significance. Q2) A tyre company wants to

the following: • The observations must be independent. • The observations should be drawn from normally distributed populations. • These populations should have equal variances. • The measurement scales should be at least interval so that arithmetic operations can be used with them. Parametric tests place different emphasis on the importance of assumptions. Some tests are quite robust and hold up well despite violations. For others‚ a departure from linearity or equality of variance may

Statistical average is referred to as the mean. Researchers determine the mean by dividing the sum of observed values by the number of observations (n). Field (1998) states‚ statistical average (mean)

used to measure is the standard deviation. Standard Deviation: It is a measure of the values of the variables around its mean or it is the square root of the sum of the squared deviations from the mean divided by the number of observances. The arithmetic mean of the returns may be same for two companies but the returns may vary widely. This can be illustrated with an example. Now let us take two companies A and B to calculate the expected returns. COMPANY A standard deviation is affected
