Sample mean = 985
Sample standard deviation = 10
Let as assume that sample is distributed normally.
The formula for test statistic
where,
is sample mean
μ is population mean.
s is sample standard deviation.
n is sample size.
The value of test statistic is
The p-value is
Therefore the p -value is less than 0.001.
Answer:
10
Step-by-step explanation:
Given expression is .
is a complex expression.
The value of<em> i </em>is –1.
By definition of absolute value,
Now, substitute in the above formula.
(since <em>i </em>= –1)
(since
and
)
(Square root of 100 is 10)
= 10
Hence, the value of the expression is 10.
