Decide whether you can use the normal distribution to approximate the binomial distribution. If you can, use thenormal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why anduse the binomial distribution to find the indicated probabilities.A survey of adults found that 8% say their favorite sport is auto racing. You randomly select 400 adults and ask themto name their favorite sport. Complete parts (a) through (d).Determine whether a normal distribution can be used to approximate the binomial distribution. Choose the correctanswer below.A. Yes, because both np ≥5 and nq ≥ 5.OB. No, because nq <5.OC. No, because np < 5.(a) Find the probability that the number of people who say auto racing is their favorite sport is at most 38.(Round to four decimal places as needed.)Correct

A survey was conducted two years ago asking college students their top motivations for using a credit card. You think this distribution has changed. You randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the distribution? Use a = 0.025.

A survey of 30 people was conducted about how many siblings they had. A graph was created that showed the percentage of the survey group, which had each number of siblings. The "frequency" column in the table shows the number of responses that having a certain number of siblings received. Using appropriate and precise statistical terminology, describe the distribution and provide an explanation for the distribution being a certain way.

Using the x²-test check which distribution better fits the data (e.g., results in smaller chi-square statistic). For the negative binomial use r=4 and p = 0.44, and for the Poisson use λ = 4.6.
The average fruit fly will lay 375 eggs into rotting fruit. A biologist wants to see if the average will be greater for flies that have a certain gene modified. The data below shows the number of eggs that were laid into rotting fruit by several fruit flies that had this gene modified. Assume that the distribution of the population is normal. 379, 406, 378, 394, 369, 369, 402, 383, 367, 357, 401, 407, 357, 394, 367 What can be concluded at the the a = 0.05 level of significance level of significance? a.
