A gene that influences coat color in domestic cats is located on the X chromosome. A female cat that is heterozygous for the gene (XBXO) has a calico-colored coat. In a genetics experiment, researchers mate a calico-colored female cat (XBXO) with an orange-colored male cat (XO) to produce an F1 generation. The researchers record observations for the cats in the F1 generation and plan to use the data to perform a chi-square goodness-of-fit test for a model of X-linked inheritance. The data for the chi-square goodness-of-fit test are presented in Table 1.
The researchers calculate a chi-square value of 4.6 and choose a significance level of p=0.05. Which of the following statements best completes the chi-square goodness-of-fit test?
answer choices
The null hypothesis can be rejected because the chi-square value is greater than the critical value.
The null hypothesis can be rejected because the chi-square value is less than the critical value.
The null hypothesis cannot be rejected because the chi-square value is greater than the critical value.
The null hypothesis cannot be rejected because the chi-square value is less than the critical value.
