Assuming The Three Conditions Are Met, Z Value Is Calculated By Looking At The Standard Deviation Between The Sample Statistic And The Population Proportion.
X2 = σ ( (o. The p value is obtained from z table for above z value, which is 0.4840, i.e., roughly 48%. For z test, the mean is not considered, instead, we take the proportions to calculate p value.
