PLEASE HELP! I don't know how to find the sample mean in this example because there is no data set. A random sample of 45 Hollywood movies made since 2010 is 130.5 minutes with a sample standard deviation of 13.8 minutes. Construct a 95% confidence interval for the true population mean length of all Hollywood movies since 2010.

what is the sample mean?

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

the correct answer is x/3+10≥32

hope this !

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
