\[\sum_{n=1}^{7} 2(-2)^{n-1}\]
<span>The
population standard deviation is unknown, sample size is less than 30,
and the population has a normal or near-normal distribution</span>.
<span> f (x)= 10-x³.
f(2) means the value of the function when x=2.
So, we need to substitute 2 instead of x.
f(2) = 10 - 2³ = 10-8 =2
f(2) = 2
