The sound intensity of a certain type of food processor in normally distributed with standard deviation of 2.9 decibels. If the
Maru [420]

Answer: (48.41,\ 52.19)

Explanation:

The confidence interval for population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n=9

Sample mean : \ovreline{x}=50.3\text{ decibels}

Standard deviation : \sigma=2.9\text{ decibels }

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=z_{0.025}=1.96

Now, the 95% confidence interval estimate of the (true, unknown) mean sound intensity of all food processors of this type :-

50.3\pm (1.96)\dfrac{2.9}{\sqrt{9}}\\\\\approx50.3\pm1.89\\\\=(50.3-1.89,\ 50.3+1.89)=(48.41,\ 52.19)

A microwave oven operates at 2.50 GHzGHz . What is the wavelength of the radiation produced by this appliance? Express the wavel
sattari [20]

Answer:

The wavelength is \lambda  =  1.2  * 10^8 nm

Explanation:

From the question we are told that

   The frequency of operation of the microwave is  f =  2.50 GHz  =  2.50 *10^{9} \ Hz

     Generally the wavelength is mathematically represented as

          \lambda  =  \frac{c}{f}

Here c is the speed of light with value c =  3.0 *10^{8} \  m/s

So  

         \lambda  =  \frac{3.0 *10^{8}}{  2.50 *10^{9}}

=>       \lambda  =  0.12 \  m

converting to nanometer

           \lambda  =  1.2  * 10^8 nm
