The average fruit fly will lay 389 eggs into rotting fruit. A biologist wants to see if the average will be fewer 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. 358, 388, 362, 382, 371, 385, 384, 393, 403, 389, 405 What can be concluded at the the a = 0.10 level of significance level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho? Select an answer♥ H₁ PS Select an answer c. The test statistic ? (please show your answer to 3 decimal

About 2% of the population has a particular genetic mutation. 800 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 800.

About 2% of the population has a particular genetic mutation. 900 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 900.

About 5% of the population has a particular genetic mutation. 600 people are randomly selected.Find the mean for the number of people with the genetic mutation in such groups of 600.

About 9% of the population has a particular genetic mutation. 600 people are randomly selected. Find the mean for the number of people with the genetic mutation in such groups of 600.

For a set of data arranged or sorted in numerical order, the value of the observation in the center is called the weighted mean. Group startsTrue or FalseTrue, unselectedFalse, unselectedGroup ends

Texting while driving has become a national focus now that cell phones are ubiquitous and texting while driving results in ever-increasing injuries and deaths. According to 2013 study, 44.5% of US Teenage drivers text while driving. You want to see how Gainesville teenage drivers compare to national teens. You randomly select 300 local high school students (ages 16-19) and ask if they have texted while driving within the past 30 days. The data is recorded in the table. Yes No 142 158 Find a 95% confidence interval for the percentage of teenage drivers who text while driving. Then explain what the confidence interval means in this context.
