1. A large furniture store has begun a new ad campaign on local television. Before the campaign, the long-term average daily sales were $24,819. A random sample of 40 days during the new ad campaign gave a sample mean daily average sale of $25,910 Does this indicate that the population mean daily sales are now more than $24,819. Test the claim at the 1% level and assume the population standard deviation is $1917? (use the Z). 2. A new bus routehas been established between downtown and booville. I've taken the bus fro many years. For the old bus route the mean waiting time between busses at my stop is 20 minutes (population mean). However the new route had had mean (X bar) of 15.1 minutes with a sample standard deviation of 6.2 minutes. = 6.2 Does this mean the mean waiting time is shorter than the old route. Check this claim at the 5% level The sample size n in the bus problem is 5. 3. The State Fish and Game Division claims 75% of the fish in a local creek are rainbow trout. A local fishing club caught 189 fish one weekend and found 125 were rainbow trout. For this problem, assume no single fish was caught more than once. Does this indicate that the prcenage of raunbow trout in the creek is not 75% (this is a p problem use the z) (FOR QUESTION 2 USE THE T) Please answer one by one and all please make sure it's clear
