(10 points; 10 minutes) 16. The data below are for a random sample of people "5 years old or less" and another random sample of people "Older than 5 years". Use the data to test the claim that the proportion diagnosed with autism among all people that are 5 years old or less is greater than the proportion diagnosed with autism among all people that are older than 5 years.

Randomly selected 20 student cars (population 1) have ages with a mean of 7 years and a standard deviation of 3.6 years, while randomly selected 22 faculty cars (population 2) have ages with a mean of 5.4 years and a standard deviation of 3.5 years. (For the purposes of this exercise, the two populations are assumed to be normally distributed.) 1. Use a 0.01 significance level to test the claim that student cars are older than faculty cars.

Why can't we study sedimentary rocks that are older than about 3.7 Billion Years Old (byo)? O Rock older than 3.7 billion years has too much be considered sedimentary O The earth was not stable enough for life unti entary rock could not form until then because of a different carbon ratio We do! There is lots of sedimentary rock that is older 3.8 byo rocks in Hudson Bay for ins Canada. lithosphere of the earth (the crust) is being...
Fifty years ago, only 10% of state population consisted of people older than 70 years old. A researcher plans to use a sample of n = 500 people to determine whether the population distribution has changed during the past fifty years. If a Chi-square test is used to evaluate the data, what is the expected frequency for the older-than-70 years old category? A. 20 B. 30 C. 40 D. 50 E. None of the above.
Years ago only 24% of the US. population consisted of people older than 62 years old.
