Translate the statements into a confidence interval for p. Approximate the level of confidence. In a survey of 8451 U.S. adults,
Sedaia [141]

Answer:

The  confidence interval is  0.304 <  p  < 0.324

Step-by-step explanation:

From the question we are told

      The sample proportion \r p  =  0.314

      The margin of error  is E =  0.01

The confidence interval for  p is mathematically represented as

       \r p -  E  <  p  < \r p + E

=>    0.314 -  0.01  <  p  < 0.314 +  0.01

=>   0.304 <  p  < 0.324

A block of wood 3.0 cm on each side and has a mass of 27 g. What is the density of this block.
Sidana [21]
The density is 1g/cm³. To calculate density, the equation density=mass/volume is used. You already know the mass, 27g, but you need the volume. The equation for volume is length x width x height. Plug in your side measure 3, to get 3 x 3 x 3, which is 27cm³. Now, just divide the mass by the volume. 27g/27cm³= 1g/cm³
