1. At noon a passenger train leaves the Columbus Railway station and travels due west for 2 hours. At 12:15 PM the same day a second passenger train leaves the same railway station and travels due east for 1 hour and 45 minutes at a speed 11 km per hour slower than the first passenger train. At 2:00 PM the two trains were 232 km apart. How fast

A manufacturer of salad dressings uses machines to dispense liquid ingredients into bottles that move along a filling line. The machine that dispenses dressings is working properly when 8 ounces are dispensed. The standard deviation of the process is 0.15 ounces. Suppose that the average amount dispensed in a particular sample of 50 bottles is

Compare and contrast the t-distribution to the standard normal distribution. How do degrees of freedom affect the shape of the t-distribution? Decide whether the following changes will increase or decrease power. Increasing n will _______________________ power. Increasing will ________________________ power. Increasing will

if the price of gas increased from $1.54 in 2020 to $3.07 in 2022, find the percentage increase.

A consumer group claims that the mean minimum time it takes for a sedan to travel a quarter mile is greater than 14.6 seconds. A random sample of 21 sedans has a mean minimum time to travel a quarter mile of 15.3 seconds and a standard deviation of 2.12 seconds. At =0.10 is there enough evidence to support the consumergroup's claim? Assume the

2. (11pts) A large fishing farm with thousands of fish has been treating its fish to stop a spreading fungal infection. A simple random sample of 100 fish is taken to determine the proportion that is infected in this population. A careful examination determines that 12 of the fish sampled are infected. Is there statistically significant evidence

A marketing researcher wants to estimate the mean amount spent($) on a certain retail website by members of thewebsite's premium program. A random sample of 98 members of thewebsite's premium program who recently made a purchase on the website yielded a mean of $1700 and a standard deviation of $350. Construct a 99 % confidence interval estimate
