A student has a daily reading productivity level of 1 chapter while at a computer lab, 5 chapters while at a coffee shop, and 8 chapters while at a library. If 1/12 of the day is spent at a computer lab, 1/4 at a coffee shop, and 2/3 at a library, what is the total daily reading productivity level of the student? Write the solution as a mixed number or a fraction in lowest terms.

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
