A survey of 73 students found that 37% were in favor of raising tuition to pave new parking lots. The standard deviation of the

KatRina [158]

Answer:

The value is $n_2 = 317$

Step-by-step explanation:

From the question we are told that

The sample size is n = 73

The proportion that in favor of raising the tuition is $\^{p} = 0.37$

The standard deviation is $s_1 = 0.098$

The required standard deviation $s_2 = 0.047$

Generally the requires standard deviation is mathematically represented as

$s_2 = s_1 * \sqrt{\frac{n_1}{n_2} }$

=> $\frac{s_2}{s_1} = \sqrt{\frac{n_1}{n_2} }$

=> $\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2$

=> $\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2$

=> $\frac{73}{n_2} =0.2300$

=> $n_2 = \frac{73}{0.2300}$

=> $n_2 = 317$
