Two random samples are chosen from the corresponding populations. Assume that these two samples are totally independent. The measurements obtained are as fol- lows: Sample 1 10.6 10.2 10.5 10.3 10.8 9.810.6 10.7 10.2 10.0 Sample 2 9.9 9.8 9.6 10.1 10.2 10.1 9.7 9.5 9.6 9.8 Perform a test to determine whether the population means are significantly different from each other at .05. (a) Perform a test for the homogeneity of variance between the two groups. Please set up the appropriate Ho and Ha, calculate the test statistic, find P-value or rejection and state your conclusion (b) Based on the results from part (a), perform a two sample t-test for the equality of the means (versus the two-sided alternative. Please follow similar steps as in

Small Sample Difference of Means. Company officials were concerned about the length of time a particular drug product retained its potency. A random sample of 10 bottles of the product was from the production line and analyzed for potency (labeled FRESH). A second set of 10 bottles was obtained and stored in a regulated environment for 1 year (labeled STORED). The data are given below. You can safely assume the data are distributed normally. FRESH STORED FRESH STORED 9.8 9.5...

In semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metalization. The etch rate is an important characteristic in this process and known to follow a normal distribution. Two different etching solutions have been compared, using two random samples of 10 wafers for each solution. The observed etch rates are as follows (in mils/min): Solution 1 Solution 2 9.5 10.6 10.1 10.0 9.4 10.3 10.6 10.2 9.3 10.0 10.7 10.7 9.6...

Ms. Blankenship’s tenth grade class is studying the impact of photoperiod on plant growth. Her students fill 100 paper cups with potting soil and a single pea seed. Each cup is randomly assigned to one of four growth chambers. Each of the four growth chambers has an identical artificial light source (25 watts) but each has a different light (L) : dark cycle (D). Chamber 1 is set to 24L : 0D. Chamber 2 is set to 16L : 8D....

Company officials are concerned about the length of time a particular drug retains its potency. A random sample of 9 bottles of the product is drawn from current production and each bottle divided in half. One half was analyzed for potency. The other half was stored for one year, and then analyzed. The readings obtained are as follows. Higher numbers indicate higher potency. Is the mean potency the same after one year? Test at the .05 level of significance. Bottle...
