ILI Was $1500 with a standard June the rent is normally distributed. Normal distribution B) -distribution C) Neither " 8. Find the critical t values for the following: (Section 6.2) • c=0.99 and n=103.250 dA-N =161-7699 • C=0.95 and n =16_20131 • C=0.80 and n =250 C=0.98 and n=95 Note: If you cannot find the degrees of freedom (df) on the t-distribution chart, use the lower df.
(a) find the margin of error for the values of c, s, and n, and (b) construct the confidence interval for μ using the t-distribution. Assume the population is normally distributed. 1. c=0.90, s=25.6, n=16, x= 72.1 2. c=0.95, s=1.1, n=25, x = 3.5 3. c = 0.98, s=0.9, n=12, x= 6.8 4. c = 0.99, s=16.5, n=20, x= 25.2
