Given an experiment with H0:μ=35,Ha:μ<35H0:μ=35,Ha:μ<35, and a possible correct value of 32, you obtain a sample statistic of x¯=33x¯=33. After doing analysis, you realize that the sample size n is actually larger than you first thought. Which of the following results from reworking with the increase in sample size? a.Decrease in probability of a Type I error; increase in probability of a Type II error; increase in power b.Decrease in probability of a Type I error; decrease in probability of a Type II error; increase in power c.Increase in probability of a Type I error; increase in probability of a Type II error; decrease in power. d.Increase in probability of a Type I error; decrease in probability of a Type II error; decrease in power. e.Decrease in probability of a Type I error; decrease in probability of a Type II error; decrease in power.
A sample of n = 4 scores is selected from a population with µ = 70 and s = 10. The probability of obtaining a sample mean greater than 65 is p = 0.8413. True False
You flip an unfair coin with Pr[H]=0.2 three times. Find the expected number of heads flipped.
The expected value of this estimator is ?
Suppose we wish to estimate the expectation of a random variable X with a large popula- tion. We observe n members of the population, i.e. {x;}1. Individual i is included in the sample with a probability proportional to p;. Please demonstrate that the usual sample E; ®i/Pi i=1• mean ī = n-1E, xi is no longer a consistent estimator for E[X], but ã is. E; 1/Pj vi=1
4) What number of drones N makes your second-morning observations as likely as possible?5) Assuming again that the probability that N = n is proportional to the probability of observing this specificdata on the second day, find again the smallest nmax so that P (N ≤ nmax) = 0.95.
An experiment consists of flipping a weighted coin with Pr[H]=0.6. The experiment ends when either heads is flipped 3 times or tails is flipped. What is the probability that heads was flipped at least once given the coin was flipped at most two times?
