This test is a simple statistical test to evaluate the amount of deviation from the expected equal frequency ratio in cach class The chi-square test can be used to test any ratio goodness of fit. The calculated chi-square value is obtained by the formula: X =E (O-E)/E. Where, O- observed number on the actual cross; observed value E- calculated or expected frequency (from the corresponding theoretical cross) E- summation symbol which means that you'll have to perform a calculation for every single data item in your data set. ОВJЕСTIVES The students should be able to: a. To compare phenotypic data derived from actual crosses to expected values using the Chi-square test b.

We take a sample of 25 voters and find that 20% of them support the reelection of the President. Do we have sufficient evidence to suggest that the true proportion of voters supporting reelection is less than claimed? Use α = 0.1.Note that we are performing a test of hypothesis about a population proportion. Since the population size is known and finite we use a hypergeometric distribution to compute the p-values.Enter in the important parameters for this hypergeometric distribution.Population size = N =Proportion of successes in the population = p0= %Number of successes in the population = M =Sample size = n =Proportion of successes in the sample = p̂ = %Number of successes in the sample = X =p-value = (6 decimal places)Conclusion:At the ? = 0.1 level there --- is not is enough evidence to conclude that the true…
