Ciara, an ornithologist (a person who studies or is an expert on birds.), has 4 bird feeders at separate locations. She wonders if birds are equally likely to visit each of the feeders (each expected proportion to be 25%) . She recorded data for a sample of 350 recent visits. Here are the results: Feeder #1 #2 #3 #4 Observed visits 80 90 92 88 Use Rguroo: Analysis-> analytics-> Goodness of Fit If Ciara performs a goodness-of-fit, can she determine if these results suggest that birds visit one specific feeder is different or the same from the other feeders. Use Rguroo to test at 5% significance level. Ho : P1 = p2 = p3 = p4 = 25% Ha : At least one proportion is different than expected. a) The value of the observed test statistic is Xobserved = Round to two decimal places. b) The Xcritical = Round to two decimal places. c) Result: Since Xobserved Xcritical we fail to reject the null.
