May i please get help with this

Genetic Variation in Fast-Twitch Muscles Chi-square tests are common in genetics. A gene called ACTN3 encodes a protein which functions in fast-twitch muscles. People have different variants of this gene, classified as RR, RX, or XX. Computer output is shown for testing whether the proportions in these categories are 0.25 , 0.5 , and 0.25, respectively. The observed counts come from a study conducted in Australia. Chi-Square Goodness-of-Fit Test for Observed Counts Test Contribution Category Observed Proportion Expected to Chi-So RR 130 0.25 109 4.04587 RX 226 0.50 218 0.29358 XX 80 0.25 109 7.71560 N DF Chi-Sq P- value 436 2 12.0550 0.002 (a) What is the sample size? n = i (b) What is the observed number of people with the variant RR for this gene? What is the expected number of people in this group under HO? Observed = i Expected = i (c) Which variant contributes the most to the chi-square statistic? XX V For this variant, is the observed value greater than or less than expected? Less than (d) What are the degrees of freedom for the test? Degree of Freedom = i (e) What is the p-value? p-value =
