For which of the following is a t-test appropriate for performing a hypothesis test? Select the correct answer below: O A sample mean of 33 pounds and a standard deviation of 3 pounds are obtained using a simple random sample of 18 mountain bikes from the most popular bicycles offered by major retailers having approximately normally distributed weights. The population standard deviation is 2.4 pounds. O A simple random sample of 12 two-inch candles is taken from the candles offered...

In performing a hypothesis test where the null hypothesis is that the population mean is 4.8 against the alternative hypothesis that the population mean is not equal to 4.8, a random sample of 25 items is selected. The sample mean is 4.1 and the sample standard deviation is 1.4. It can be assumed that the population is normally distributed. The observed "t" value for this problem is _______.
