Answer:

213 samples needed for 99% confidence interval

Step-by-step explanation:

We know that:

minimum size of sample needed to be sure about total measurement less than 3.5 degree is given as

$n = [\frac{z_{\alpha/2}\times s}{E}]^2$

where,

s is standard deviation = 19.8 degree

E IS MARGIN OF ERROR = 3.5 degree

$z _{\frac{\alpha}{2}}$ right tail critical value of

Z $z _{\frac{\alpha}{2}} = z _{\frac{0.01}{2}} = z_{0.005} = 2.58$

so, minimum size of sample needed is

$n = [\frac{2.58\times 19.8}{3.5}]^2$

n = 213.02

Therefor 213 samples needed for 99% confidence interval
