Hello... There are two homework problems that I am having trouble with. I have no work to show because I don't know where to start let alone finish. Can someone who has time please look these over and show me step by step what they did to get the answer and what the answer is. Thank you so much
1. Research has found that 26% of all car seats are improperly installed. If the installation of 18 car seats is checked find the probability that : 1. exactly 5 of the seats will be installed incorrectly and 2. more than 10 of the seats will be installed incorrectly.
2. A local pub owner claims that his bar sells an average of 306 bottles of Corona beer a day. His "Silent" partner believes that the owner is overestimating this total. A random sample of 60 days, finds the average Corona sales to be 282 bottles a day with a standard deviation of 24 bottles. Based on this data and using a significance level of .05 is the partners claim true ?
