Type 1 a supernova can also used as standard candle to measure distances to galaxies where telescopes can not resolve individual stars...As light gets dimmer in the relation inverse square law, both Cepheid variable and Type 1 A supernova can be used as standard candle to measure distances. Type ! A supernova occurs in binary Star system and they are reliable as standard candle.

What is the range of the function $y={x}^{2}$?

The domain and range of $y=\mathrm{sin}x$ is

A)$R,[0,\mathrm{\infty}]$

B)$R,[-1,1]$

C)$R,[-\mathrm{\infty},\mathrm{\infty}]$

D)$R,[1,\mathrm{\infty}]$Mean of the squares of the deviations from mean is called the:

Variance

Standard deviation

Quartile deviation

A local newspaper in a large city wants to assess support for the construction of a highway bypass around the central business district to reduce downtown traffic. They survey a random sample of 1152 residents and find that 543 of them support the bypass. Construct and interpret a 95% confidence interval to estimate the proportion of residents who support construction of the bypass.
