Assume that we want to construct confidence interval. Do one of the following, as appropriate: (a) find the critical value t/2, (b) find the critical value z/2, or (c) state that neither the normal distribution nor the t distribution applies. Here are summary statistics for randomly selected weights of newborn girls: n = 220, x= 29.5 hg, s= 6.8 hg. The confidence level is 90%. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. tu/2= (Round to two decimal places as needed.) O B. Zu/2= (Round to two decimal places as needed.) OC. Neither the normal distribution nor the t distribution applies.

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.
