HELP ME ANSWER THIS PLZ!!! A computer was used to simulate choosing 250 SRSs of size n = 80 from a population of 4,000 beads. It is claimed that 38% of these beads are red. The dotplot shows p hat, the sample proportion of beads that are red, for each of the 250 simulated samples. A dotplot titled simulated sample proportions. A number line goes from 0.20 to 0.55 and is labeled p hat = simulated sample proportion of red beads in this bin. The data is highest at the middle of the number line and lower on the ends. Would it be surprising to get a sample proportion of p hat = 0.50 or larger in an SRS of size 80 when p = 0.38?

Sorry I don’t know I needed points

Answer: D. Yes. Out of the 250 samples, only 1 resulted in a proportion of 0.5 or more, so this is highly unlikely.
