Does soil without nitrogen decrease the weight of worms compared with soil with nitrogen? the weight of 14 randomly selected worms is acquired, seven in soil with nitrogen and seven in soil without nitrogen. the mean weight of worms in soil without nitrogen was 35.3 micrograms whereas the mean weight of worms in soil with nitrogen was 45.3 micrograms. a researcher randomized the data over 100 trials, and the difference of means for each trial is shown in the dot plot below. what can the researcher conclude from this study?

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
