Answer:
The 95% confidence interval is
The pivot function used is
Step-by-step explanation:
From the question we are told that
The data given is 246 242 248 245 250 244 252 248 248 247 250 248 246 242 248 244 245 246 250 242
The sample size is
Given that the confidence level is 95% then the level of significance is
The degree of freedom is mathematically represented as
From the student t-distribution table the critical value of is
The mean is mathematically represented as
The standard deviation is mathematically represented as
The margin of error is mathematically represented as
The 95% confidence interval is mathematically represented as
=>
=>
The pivot function used is
<u><em>9 is the greatest common factor correct answer.</em></u> First you had to find prime factorization of 9: 1, 3, 9, 3²=3*3=9. And then, you had to find prime factorization of 27: 1, 3, 9, 27, 3³=3*3*3=27. The greatest common factor of 9 and 27 is 9 is the final answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
