During the first 15 weeks of the 2016 season of a certain professional football​ league, the home team won 135 of the 233 ​regular-season games. Is there strong evidence of a home field advantage in this​ league? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before proceeding with the hypothesis test. Determine the hypotheses for this test.​ (The proportion of home teams winning is denoted by​ p.)   H0​: p equals= less than< greater than> equals= not equals≠ nothing HA​: p not equals≠ equals= not equals≠ greater than> less than< nothing ​(Type integers or​ decimals.) Calculate the test statistic.   z=nothing ​(Round to two decimal places as​ needed.) Find the​ P-value.   ​P-value=nothing ​(Round to three decimal places as​ needed.) State the conclusion of the test.   Because the​ P-value is low, low, high, reject reject fail to reject H0. These data show that there is is is not sufficient evidence of a home field advantage in the professional football league.

Bar Graphs

A bar graph is a chart or graphical representation of data. A bar chart, also known as a bar graph, is a graph or chart that displays categorical data using rectangular bars with heights or lengths equal to the values they represent. Typically, bar graphs show categorical and numerical variables grouped in class intervals. A bar graph is useful for comparing and analyzing a set of data.
