How is this done in R-studio? I have been trying to figure it out but I am getting more and more confused.

While imprisoned by the Germans during World War II, the English mathematician John Kerrich tossed a coin 10,000 times and obtained 5067 heads. Let p be the probability of a head on a single toss. We wish to check if the data are consistent with the hypothesis that the coin was fair.

a) Set up the hypotheses. Why should the alternative be two-sided?

b) Calculate the p-value. Can you reject H0 at the 0.05 level? Justify your answer.

c) If you reject the null hypothesis what does that mean?

d) Find a 95% confidence interval for the proportion of heads for Kerrich’s coin. Is this consistent to the significance test in part (b)?

I was trying to figure out the flow of electrons in a battery connected to a circuit. Conventionally, current is from the (+) terminal to the (-) terminal of the battery. Realistically it flows the other way round; from the (-) terminal to the (+) terminal. My question is, assuming electron flow is from the (-) terminal, would the battery's cathode be located at the (+) terminal and it's anode at the (-) terminal or would it be vice versa?...

I am trying to figure out how to properly execute a while loop and a do/while loop in the same program using java. I am stuck at just writing the while loop. I made a condition but I can't figure out how to get it to loop if the condition is true?? Also I have to write a do/while loop in the same program. here are the details: This lab demonstrates the use of the While Loop and the Do...

I am trying to figure out the social security tax for the employees in this problem, becuase I have to post it all in a chart. I have tried multiplying by the 6.2 tax rate but my program says my answer is wrong. So, is there a different way to calculate social security tax or is there something that I am missing that the problem is asking me to do? I am not looking for answers, but just a clear...

Hello, i have this excersice in R studio Write a function in R that generates simulations of a Poisson random variable as follows: define I = [λ], and use p_i + 1 = λp_i / (i + 1) to determine F recursively. Generate a random number U, determine if X≤I by comparing if U≤F (I). If X≤I searches downwards starting at I, otherwise it searches upwards starting from I + 1. Compare the time it takes for the two algorithms...
