Marla is studying the sodium content of cold cuts. A random sample of 8 52-gm samples of smoked beef produced sample mean 14.04 gm of sodium with sample standard deviation 0.50 gm. An independent random sample of 6 52-gm samples of smoked turkey produced sample mean 13.52 gm sodium with sample standard deviation 0.75 gm. Test the claim that there is a difference in the mean sodium content of the above brands of smoked ham and smoked turkey. Use a 5% significance level. Assume that population variances are not equal.
