The following results come from two independent random samples taken of two populations. Sample 1 Sample 2 n1 = 40 n2 = 35 x?1 = 13.6 x?2 = 11.8 ?1 = 2.5 ?2 = 3.4 a. What is the point estimate of the difference between the two population means? (to 1 decimal) b. Provide a 90% confidence interval for the difference between the two population means (to 2 decimals). c. Provide a 95% confidence interval for the difference between the two population means (to 2 decimals).

Consider the following data for two independent random samples taken from two normal populations. $$ \begin{array}{l|rrrrrr} \text { Sample 1 } & 10 & 7 & 13 & 7 & 9 & 8 \\ \hline \text { Sample 2 } & 8 & 7 & 8 & 4 & 6 & 9 \end{array} $$ a. Compute the two sample means. b. Compute the two sample standard deviations. c. What is the point estimate of the difference between the two population means? d. What is the $90 \%$ confidence interval estimate of the difference between the two population means?
