Include how each is calculated.Suppose the probability of erroneously transmitting a single digit is P=0.03. Compute the probability of transmitting a 4-bit code word with (a) at most one error, and (b) exactly four errors.find the conditional frequency function of X given that Y =4 , and the conditional frequency function of Y given X =2.
- A researcher wishes to see whether there is a difference in the weight loss ofwomen following one of the three special diets. Women are randomly assignedto the three groups and placed on the diet for 2 months. The weight losses (inpounds) are shown here. At α = 0.05, can the researcher conclude that there isa difference in diets?in experiment on pea-breading, mendel got following frequencies of seeds: 315 round and yellow, 101wrinkled and yellow, 108 round and green: total 556. Theory predicts that the frequencies should be in the frequencies should be in the proporation 9:3:3:1 . Examine the correspondence between theory and experiment. (chi- square at 3 degrees of freedom at 5% level of signifiance is 7.812)Suppose that a researcher is interested in differences between young adults and older adults with respect to social media preferences. The researcher asked participants to indicate their preference for a specific social media application by checking all that apply among the following: Twitter, Facebook, and Snapchat. The researcher observes the following: Identify the assumptions of the chi-square test that would be violated if the researcher performed a chi-square test on the frequencies in the table.
