Answer:

y=-2

Step-by-step explanation:

3y+2=-2+y

subtract the 1y from both sides leaving you with 2y+2=-2

In a sample of 115 115 curtains, the average length was found to be 32.2in. 32.2 ⁢ in. With a standard deviation of 0.8 0.8 . Gi
pentagon [3]

Answer:

The point estimate for the population standard deviation of the length of the curtains is 8.58in.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

s = 0.8, n = 115

The point estimate for the population standard deviation of the length of the curtains is \sigma. So

s = \frac{\sigma}{\sqrt{n}}

\sigma = s\sqrt{n}

\sigma = 0.8\sqrt{115}

\sigma = 8.58

The point estimate for the population standard deviation of the length of the curtains is 8.58in.
