Hello, i need help from this question:

analyzing a simple random sample of 50 survivors.

Survivor Data(gender):

male female female female female female male female male female male female female female female female female male male female female female female male male female female male male female female female female female female female male female female female female female female male male female female female male male

1) Provide an estimate of the proportion of survivors who were female?

2) Construct an interval that will encompass the true value of the proportion of survivors who were females with probability 0.9.

3) In order for the previous interval to be reliable, it is assumed that the sampling distribution of the sample proportion be approximately Normally Distributed. Confirm whether this assumption is justified and explain your reasoning.

4) Since there were not enough life-boats to accommodate every passenger, when it came time to evacuate the ship the time-honored tradition of "women first" was practiced when determining who would be granted a spot on a life-boat. Based on the previous results, is there statistical evidence to conclude the prior practice was indeed adhered to? Explain your rationale.
