A group of students estimated the length of one minute without reference to a watch or clock, and the times (seconds) are listed below. Use a 0.05 significance level to test the claim that these times are from a population with a mean equal to 60 seconds. Does it appear that students are reasonably good at estimating one minute? 68 81 38 67 45 21 61 62 64 45 65 72 96 92 63 Assuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses? YA. Ho: u= 60 seconds O B. Ho: µ= 60 seconds H: u> 60 seconds H1: µ#60 seconds O D. Ho: µ# 60 seconds H1:H= 60 seconds O C. Ho: H= 60 seconds H,:µ< 60 seconds Determine the test statistic. (Round to two decimal places as needed.)

Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.
