4y = 42 - 3y

First, add '3y' to both of the sides.
4y + 3y = 42
Second, add '4y + 3y' to get '7y'.
7y = 42
Third, divide both sides by '7'.
y =  \frac{42}{7}
Fourth, how many times does 7 go into 42? 42 ÷ 7 = '6'.
y = 6

Answer: y = 6

Bring all the variables with y to one side:
4y = 42 - 3y
4y + 3y = 42 - 3y + 3y
7y = 42

Divide both sides by 7 to get the y alone:
7y ÷ 7 = 42 ÷ 7
y = 6

In an effort to estimate the mean of amount spent per customer for dinner at a major Lawrence restaurant, data were collected fo
larisa86 [58]

Answer:

The 99% confidence interval for the population mean is 22.96 to 26.64

Step-by-step explanation:

Consider the provided information,

A sample of 49 customers. Assume a population standard deviation of $5. If the sample mean is $24.80,

The confidence interval if 99%.

Thus, 1-α=0.99

α=0.01

Now we need to determine z_{\frac{\alpha}{2}}=z_{0.005}

Now by using z score table we find that  z_{\frac{\alpha}{2}}=2.58

The boundaries of the confidence interval are:

\mu-z_{\frac{\alpha}{2}}\times \frac{\sigma}{\sqrt{n} }\\24.80-2.58\times \frac{5}{\sqrt{49}}=22.96\\\mu+z_{\frac{\alpha}{2}}\times \frac{\sigma}{\sqrt{n} }\\24.80+2.58\times \frac{5}{\sqrt{49}}=26.64

Hence, the 99% confidence interval for the population mean is 22.96 to 26.64
