The Coffeebuck is a famous café with latte would like to open a new branch at Kuala Lumpur. The taste consistency of the latte is very important to make sure the quality of latte remains. They believe that each latte has an average of 4 oz of espresso. A random sample of 25 lattes shows a mean of 4.6 oz of espresso and a standard deviation of 0.22 oz. a) State the hypothesis (null and alternative) b) Compute the test statistics and determine the critical value (Use ? = 0.05 level of significant). c) Determine whether the null hypothesis is rejected or not rejected.

1- A researcher makes a research about the life time of batteries which have a normal distribution. In order to understand the life time of batteries s/he randomly selected 49 batteries and calculate the sample mean as 48 hours and standard deviation of 5 hours. Construct 90 % confidence interval for the true population mean of life time of batteries.
24. An inspector is interested in finding a 90% confidence interval for the mean number of rodent hairs that are contained in 700 gram containers of peanut butter that are produced in the factory. The number of hairs found in each the 16 containers inspected is shown below. 7,5,6,7,8,2,11,0,4,9,10,7,3,1,14,8 Assume a normal distribution and round your answers to two decimal places. A. The sampling distribution follows a distribution. B. With 90% confidence the population mean number of rodent hairs per container for all container produced in the the factory and hairs. C. If many groups of 16 randomly selected peanut butter containers are inspected, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of rodent hairs per container and about percent will not contain the true population mean number of rodent hairs per container.
Choose the correct alternative hypothesis for the following situations. Check the circle. The null hypothesis is given. a) An ambulance service is considering replacing its ambulances with new equipment. If $52.00 is the average weekly maintenance cost of one of the old ambulances and u is the average weekly maintenance cost it can expect for one of the new ones, what alternative hypothesis should it use if it wants to buy the ambulances only if it can be shown that this will significantly reduce the average weekly maintenance cost?
