To calculate the required sample size, what value ofp* should we use in the formula below to calculate a 90% confidence interval within 1.69 percentage points? Give exact answer as a decimal.

Answer 1

to calculate the 90% confidence level within 1.69 % points we take the value of P to be 0.05%

Step-by-step explanation:

The p-value can simply be explained as the probability, under which the null hypothesis about the unknown distribution in question of the random variable, for which the variate to be observed as a value equal to or more extreme than the value observed.

A p-value less than or equals to 0.05 is a statistical significance. It shows strong evidence against the null hypothesis, which is shows clearly that there is less than a 5% probability the null is correct.
