The answer for that problem is z =12+6
Answer:
Option d: Your friend is wrong, the statement should be revised as "the probability of obtaining a sample mean of 105 or more extreme from a random sample of n = 40 when the true population mean is assumed to be 100."
Step-by-step explanation:
We are given;
Null hypothesis; H0 : μ = 100
Alternative hypothesis; HA : μ ≠ 100
Sample mean; x = 105
Sample standard deviation; s = 10
Sample size; n = 40
p - value = 0.0016
Looking at the options, the first option is wrong because the sample size is not irrelevant her since it's more than 30.
The second option can't be correct because they just told us he is right without giving explanation.
The third option is wrong because 100 is the true population mean and not 150.
Thus we are left with Option D as the correct answer.
Answer:
A) a small variance for the difference scores and a small standard error
Step-by-step explanation:
Since the difference scores are obtained by subtracting one variable form another, if the difference scores are consistent between treatments, then the variance will be small. The higher the variance, the higher the standard error. So if the variance is small, then the standard error will also be small.
It should represent Sydney's age, right? The equation would be 3s-5 I'm 99% sure lol
Let s = sale
Let h = hours
The ratio is s to h, which can be written as a fraction as 24/6.
