Upper H 0 : pequals 0.512Upper H 1 : pgreater than 0.512 C. Upper H 0 : pequals 0.512Upper H 1 : pless than 0.512 D. Upper H 0 : pnot equals 0.512Upper H 1 : pequals 0.512
Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is negative .-.46 (Round to two decimal places as needed.)
Identify the P-value for this hypothesis test. The P-value for this hypothesis test is _____
Please show step by step to find the P-value, I am getting really confused on how to do it.I need someone to explain how i used the z-score table method and the calculator method. Specifically please tell me what do I type in the calculator,

4. A random sample of 860 births at St. Jude’s Hospital included
426 boys. The national proportion of newborn boy babies is 51.2%.
Use a 0.01 significance level to test the claim that the proportion
of newborn boy babies at this hospital is different than the
national average.
