The mode phenotype code is(Use a comma to separate answers as needed.)O B. There is no mode.(d) The midrange of the phenotype codes is(Type an integer or a decimal.)Do the measures of center make sense?A. Only the mode makes sense since the data is nominal.O B. Only the mean, median, and mode make sense since the data is numerical.C. Only the mean, median. and midrange make sense since the data isnominal.D. All the measures of center make sense since the data is numericalLNext000 0 possibleA magazine published a list consisting of the state tax on each gallon of gas. If weadd the 50 state tax amounts and then divide by 50, we get 27.3 cents. Is the valueof 27.3 cents the mean amount of state sales tax paid by all U.S. drivers? Why orwhy not?Choose the correct answer below.O A. Yes, the value of 27.3 cents is the mean because a mean is found bysumming all sample values and then dividing the by total number ofvalues.O B. No, the value of 27.3 cents is not the mean because the 50 amounts areall weighted equally in the calculation, but some states consume moregas than others, so the mean amount of state sales tax should becalculated using a weighted mean.OC. No, the value of 27.3 cents is not the mean because it is the median thatis found by summing all sample values and then dividing the by totalnumber of values.O D. Yes, the value of 27.3 cents is the mean because it is a measure of centerand all measures of centers can be refered to as either an average or amean.Next

The U.S. National Center for Health Statistics complies birth statistics and publishes the results in vital statistics of the United States. The Center has historically believed that the mean of all newborns in the U.S. has been no less than 6.95 pounds. A sample of babies is selected so that the center can revise its belief. The following birth weights, in pounds are recorded: 7.4, 6.0, 8.6, 4.5, 2.0, 7.9, 4.0, 2.6, 5.9, 7.3, 7.3, 7.0, 6.3, 8.1, 7.1, 7.3, 6.6, 5.2, 9.8, 8.0, 10.9, 6.5, 3.8, 5.0, 8.0 a). At 5% level of significance, do these data provide sufficient evidence to refute the Center’s belief? Your conclusion must be in terms of the P-Value as well as setting up a Rejection Region. You must show all necessary work. b). Which statistical distribution should be applied in this situation and why? Explain carefully.
