Psychology experiments sometimes involve testing the ability of rats to navigate mazes. The mazes areclassified according to difficulty, as measured by the mean length of time it takes to find the food at the end.One researcher needs a maze that will take rats an average of one minute to solve. He tests one maze on18 rats. Is there evidence that this maze is "too easy" or "too difficult" (implying taking something other thanone minute to solve, on average)? The times to complete the maze (in seconds) for the 18 rats are given inthe MAZE data set on Canvas and in the ST 351 online class folder on the k drive. Suppose the populationstandard deviation ( X ), is 2 seconds.

State the null and alternative hypotheses in statistical notation and in words.
