Select the null and the alternative hypotheses. OHO: Group types do not differ in mean number of offspring. OHO: At least one group differs in mean number of offspring. Ha: Group types differ in mean number of offspring. Ha: At least one group differ in mean number of offspring. A scientist tested the effects of sex ratio on the fertility of female flower beetles (Tribolium castaneum). They created groups of beetles that had equal numbers of males and females ("unbiased" sex ratio), more males than females ("male-biased"), or more females than males("female-biased"). They measured the number of offspring per female in each group. Answer the following questions. Group Type Unbiased Raw data (g) 77, 74, 70, 122, 69 Male-biased 113, 118, 89, 201, 151 Female-biased 75, 48, 64, 52, 61
