Not sure what the question is, but this is 4/10 or 0.4.
Answer: Estimated standard error for the sample mean difference would be 1.
Step-by-step explanation:
Since we have given that
Mean of MD = 4.90
So, Sum of difference would be

S = 288
n = 9
We need to find the standard error for the sample mean differences.
Estimated standard error for the sampled mean difference would be

Hence, estimated standard error for the sample mean difference would be 1.
Answer:
2 minutes
Step-by-step explanation:
You can make an equation to model the question.
y=60 initial starting value,
y=(750-720)x, plug in 60 for y,
60=30x, x = 2 minutes
9.73, or 9.73x10^-3, hope this helped!
I’m confused there are no numbers ?
