Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

The road octane numbers of two different formulations of gasoline are being studied. A random sample of size n, = 15 is taken for formulation 1;
while, for formulation 2, the random sample size is na = 20. The variance of the octane number for formulation 1 is a, 2 =1 5, and for formulation
2, it is a,2 =1 2. The mean octane numbers observed are x, = 89.6 and x, = 92.5. Assume normality. What is the upper limit of a 95% two-
sided confidence interval on the difference in mean octane number (u, - H)?

Let x = age in years of a rural Quebec woman at the time of her first marriage. In the year 1941, the population variance of x was approximately ?2 = 5.1. Suppose a recent study of age at first marriage for a random sample of 41 women in rural Quebec gave a sample variance s2 = 2.9. Use a 5% level of significance to test the claim that the current variance is less than 5.1. Find the value of the chi-square statistic for the sample. (Round your answer to two decimal places.)

Suppose a population has a standard deviation of 10. Assume that we continue to select groups of 100 individuals from the population and calculate the sample means. The variation among all these sample means is measured by o/v(n). Compare the distribution of single observations (x) with that of the means x. (That is, compare the histograms of x and x.) We can conclude that the distribution of x is spread out. In other words, averages vary much than individual observations. less; less less; more more; less more; more
