Q. A firm is manufacturing two brands, A and B, of battery cells. It claims that the average life of brand A cells is more than that of brand B cells by 100 hrs, the variances of the two brands being the same. To maintain this standard, two independent samples of 12 cells of each brand are selected on the 20th of every month and a t value of the difference of sample means computed. The firm is satisfied with its claim if the computed t value falls between ħt0.025. A sample of 12 cells of brand A gives a mean life of 1200 hrs and variance of 49 hrs, and that of 12 cells of brand B gives a mean life of 1095 hrs and variance of 64 hrs. Comment on the outcome of the sample results.
Answer. ........

Q. Write a note on measures of central tendency.
Answer. Measures of central tendency are descriptive statistics that summarize the data with a single number that represents the most typical score within a set of data. We use measures of central tendency because we typically believe that most scores on a scale or responses to an item cluster around the typical or most common score or response in the data set. Consequently, a measure of central tendency is a convenient statistical tool for indicating the most typical score in a set of data. Selecting an appropriate measure of central tendency depends on the measurement scale used to represent a particular variable........... Measures of central tendency identify the middle or centre of a set of data. There are three types: Arithmetic average or mean – the total of items or scores in a set divided by the number of individual items in the set. It may give a distorted picture because of large items at either end of the scale. Median – the middle item in a range of items (often used in pay surveys when the arithmetic mean is likely to be distorted). Mode – the most commonly occurring item in a set of data......... The following are the few requirements to be satisfied by an average or a measure of central tendency: It should be rigidly defined The definition of an average should be clear and rigid so that there must be uniformity in its interpretation by different decision-makers or investigators. There should not be any chance for applying discretion; rather it should be defined by an algebraic formula.........
