Solve the inequality. Graph the solution. (If you can, please show how you solved the problems and which direction the line points to on the number line) 1. x/4 ≤ -18

2. -3q ≥ 91.5

3. -4p < 2/3

4. -8 ≥ 1.6m

5. -r/4 ≤ -10

6. -t/5 > 2.5

7. -2 ≥ q/-0.3

(I know these are a lot of questions, but I really need help)

Abottled water distributor wants to estimate the amount of water contained in 1-gallon bottles purchased from a nationally known water bottling company. the water bottling company’s specifications state that the standard deviation of the amount of water is equal to 0.02 gallon. a random sample of 50 bottles is selected, and the sample mean amount of water per 1-gallon bottle is 0.995 gallon a. construct a 99% confidence interval estimate for the popula-tion mean amount of water included in a 1-gallon bottle. b. on the basis of these results, do you think that the distributor has a right to complain to the water bottling company? why? c. must you assume that the population amount of water per bottle is normally distributed here? explain. d. construct a 95% confidence interval estimate. how does this change your answer to (b)?
