Question

Samples of DNA are collected and the four DNA bases of A, G, C, and T are coded as 1, 2, 3, and 4 respectively. The results are listed below: 2 3 1 3 4 2 3 3 4 1 3 2. Construct a 98% confidence interval estimate of the mean. Listed below are speeds (mi/h) measured from southbound traffic on I-280 near Cupertino, California. This simple random sample was obtained at 3:30 pm on a weekday: 62 65 68 69 63 68 58 57 61 66 62 63 72. Use the sample data to construct a 98% confidence interval estimate of the population standard deviation. Weights of pennies: 95% confidence; n=30, s=0.01199 g. Find the number of degrees of freedom. Find the critical value X^2/L and X^2/R. Construct the confidence interval estimate of the mean.
