The length of needles produced by a machine has standard deviation of 0.04 inches. Assuming that the distribution is normal, how

Lana71 [14]

Answer:

The sample size is $n = 87$

Step-by-step explanation:

From the question we are told that

The standard deviation is $\sigma = 0.04 \ inches$

The precision is $d = \pm 0.005 \ inches$

The confidence level is $C =$ 98%

Generally the sample size is mathematically represented as

$n = \frac{ Z_{\frac{\alpha }{2} } ^2* \alpha^2 }{d^2}$

Where $\alpha$ is the level of significance which is mathematically evaluated as

$\alpha = 100 - 98$

$\alpha = 2$ %

$\alpha = 0.02$

and $Z_{\frac{\alpha }{2} }$ is the critical value of $\alpha$ which is obtained from the normal distribution table as 2.326

substituting values

$n = \frac{2.326 ^2* 0.02^2 }{0.005^2}$

$n = 87$
