To test :
= 5.2 versus
:
≠ 5.2, a simple random sample of size n = 18 is obtained from a population that is known to be normally distributed.
(a) If the sample standard deviation is determined to be s = 4.9, compute the test statistic.
(b) Test this hypothesis at the = 0.05 level of significance.
Step 1 of 5) To test: = 5.2 versus: ≠ 5.2, a simple random sample of size n = 18 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 4.9, compute the test statistic. (b) Test this hypothesis at the = 0.05 level of significance. In Other Words, Probability describes how likely it is that some event will happen. If we look at the proportion of times an event has occurred over a long period of time (or over a large number of trials), we can be more certain of the likelihood of its occurrence. CAUTION! Probability is a measure of the likelihood of events that have yet to occur. Prior to flipping a coin, we say the probability of observing ahead is 1 2. However, once the coin is flipped, the probability is no longer 1 2 since the outcome has been determined.
