Answer:
i dont know
Step-by-step explanation:
i think
($94.11 + $52.75) + (-$25.20 + -$22.04 + -$8.50) =
($146. 86) - (-$55.74) =
$94.12
$94.12 is the account balance at the end of the month.
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.
From this equation, we need to find the value of m
We first isolate the variable m with its coefficient from the other values, so:
m2.8 - 4.9 = -7.11
m2.8 = -7.11 + 4.9
A negative and a positive will make a negative,so:
m2.8 = -2.21
Next we isolate the variable m completely from the other value so we divide both sides by 2.8, so
m2.8 / 2.8 = -2.21 /2.28
m = -0.78
Therefore the value of m is -0.78
