A researcher wonders if the currently-believed global male-births proportion value of approximately p = 51.2% is still correct. The researcher decides to perform a two-sided significance test, and in advance, chooses a significance-level of 1%. The researcher then randomly samples the reported birth-sex information for 1000 recent global births, and finds that exactly 551 of these babies were reported to be males. In percentage form, and rounded to three digits past the decimal point: What is the approximate P-value of this test? Include a percentage symbol at the end of your numerical answer (with no spaces).

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
