# A genetic engineer was attempting to cross a tiger and a cheetah. She predicted a phenotypic outcome of the traits she was observing to be in the following ratio: 4 (stripes only): 3 (spots only): 9 (both stipes and spots). When the cross was performed and she counted the individuals she found 50 with stripes only, 41 with spots only and 85 with both. According to the Chi-square test, did she get the predicted outcome?

Step 1

A chi-squared test is a statistical hypothesis test where the sampling distribution of the test statistic is chi-squared distribution when the null hypothesis is true. The test is used to determine if there is a significant difference between the expected frequencies and the observed frequencies in one or more categories.

Step 2

According to the question, when a tiger and a cheetah is attempted to cross, then,
