In an experiment of toss a fair coin 36 times. We want to use the normal distribution to approximate this binomial probability, what is the mean and the standard deviation to be used in normal distribution? ( Round to 1 decimal place) A) = 25, = 3.8 B) = 6, = 3 C) = 18, = 3 D) = 15, = 3.6
Given that,
Sample size (n) = 36
In fair coin P(Head) = P(Tail) = 0.5
That is p = 0.5 and (1 - p) = 1 - 0.5 = 0.5
Mean and standard deviation in Binomial distribution is,
Mean =
Standard deviation =
Hence,
Answer: C) ,

GE 5.52 Find the mean and the standard deviation. If we toss a fair coin 150 times, the number of heads is a random variable that is binomial. (a) Find the mean and the standard deviation of the sample propor- tion of heads. (b) Is your answer to part (a) the same as the mean and the standard deviation of the sample count of heads in 150 throws? Explain your answer
Toss a fair coin 4 times. Let Y be the number of heads. (a) What is the probability mass function of Y ? Compare your answer to the probability mass function of Binomial distribution. (b) What is the cumulative distribution function of Y ? (c) What is the expected value of Y ? (d) What is the variance of Y?
Suppose we toss a weighted coin, for which the probability of getting a head (H) is 60% i) If we toss this coin 3 times, then the probability of getting exactly two heads (to two decimal places) is Number ii) If we toss this coin 6 times, then the probability of getting exactly four heads (to two decimal places) is Number CI iii) if we toss this coin 8 times, then the probability of getting 6 or more heads (to...
If we toss a fair coin 50 times what is the likelihood that we land on heads 30 times or more in percentage?
Suppose that I toss a fair coin 100 times. Write 'p-hat' for the proportion of Heads in the 100 tosses. What is the approximate probability that p-hat is greater than 0.6? 0.460 0.023 0.540 We can't do the problem because we don't know the probability that the coin lands Heads uppermost 0.977
Consider the experiment of tossing a fair coin four times. If we let X = the number of times the coin landed on heads then X is a random variable. Find the expected value, variance, and standard deviation for X.
4. Toss a fair coin 6 times and let X denote the number of heads that appear. Compute P(X ≤ 4). If the coin has probability p of landing heads, compute P(X ≤ 3) 4. Toss a fair coin 6 times and let X denote the number of heads that appear. Compute P(X 4). If the coin has probability p of landing heads, compute P(X < 3).
You toss a fair coin 4 times. What is the probability that (round to 4 decimal places) a) you get all Tails? b) you get at least one Head?
A fair coin is tossed 10 times and the number of heads is counted. Complete parts (a) through (d). a. Use the binomial distribution to find the probability of getting 5 heads. (Round to four decimal places as needed.) b. Use the binomial distribution to find the probability of getting at least 5 heads. (Round to four decimal places as needed.) c. Use the binomial distribution to find the probability of getting 5 to 7 heads. (Round to four decimal...
A coin is weighted so that the probability of obtaining a head in a single toss is 0.6. If the coin is tossed 25 times, find the following probabilities. (Round your answers to fou decimal places.)
