Answer:
1.691
Step-by-step explanation:
Standard error of the mean is expressed as SEM = S/√n
S is the population standard deviation
n is the sample size (number of observation)
Given S = 27 and n = 255
SEM = 27/√255
SEM = 27/15.97
SEM = 1.691
Hence the standard error of the mean is 1.691
Answer:
The statement which could explain the effect of confounding is:
Because the weather was generally better this year compared to last year, the attendance may have increased.
Step-by-step explanation:
A confounding variable has some effect on the dependent variable. Confounding variables are the variable(s) that are additional to the independent and dependent variables in an experiment. Since the presence of confounding variables affect the variables being studied so that the results do not reflect the actual relationship, it is best to exclude or control them through randomization, restriction, and matching.
