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

Compute the difference quotient StartFraction f left parenthesis x plus h right parenthesis minus f left parenthesis x right par

kenny6666 [7]

Answer:

$\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3$

Step-by-step explanation:

$f(x)=-4x^2-3x-4$

$f(x+h)=-4(x+h)^2-3(x+h)-4$

$f(x+h)=-4(x^2+2xh+h^2)-3(x+h)−4$

$f(x+h)=-4x^2-8xh-4h^2-3x-3h-4$

$f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4-(-4x2-3x-4)$

$f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4+4x2+3x+4$

$f(x+h) - f(x)=-8xh-4h^2-3h$

$f(x+h) - f(x)=h(-8x-4h-3)$

$\dfrac{f(x+h) - f(x)}{h}=\dfrac{h(-8x-4h-3)}{h}$

$\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3$
