Ralphâs Bookstores have indicated that the annual gross revenue for their stores has a standard deviation of Ï=$50,000. Blank #1: Given a sample size of 25 and a sample mean of $270,000, create a 90% confidence interval for estimating the population mean annual gross revenue. Enter your answer as lower bound, upper bound with no extra spaces and bounds rounded to nearest whole number.
Given a sample size of 25 and a sample mean annual gross revenue of $270,000, conduct a hypothesis test with a 0.10 level of significance to show that the population mean number of boxes sold is different from $250,000.
Blank #2: Report the p-value of the test to 4 decimal places.
These procedures support each other because the value of $250,000 is (Blank #3: not in or in) the confidence interval and the p-value of the test is (Blank #4: smaller than or not smaller than) level 0.10.

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
