The lengths, in inches, of adult corn snakes are normally distributed with a population standard deviation of 6 inches and an unknown population mean. if a random sample of 18 snakes is taken and results in a sample mean of 61 inches, find the margin of error (me) of the confidence interval with a 90% confidence level. round your answer to three decimal places.

2.460

Step-by-step explanation:

The formula of Margin of Error for (n<30):-

Given : Sample size : n= 18

Level of confidence = 0.90

Significance level :

Using the t-distribution table ,

Critical value :

Standard deviation:

Then, we have

Hence, the margin of error (ME) of the confidence interval with a 90% confidence level = 2.460

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
