Hypothesis TestIt is conjectured that the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is 0.62. Of interest is to test this claim versus the alternative that the proportion ofall people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62.A simple random sample of 270 people who went trick-or-treating is selected, and 162 of them also had a pumpkin carved into a jack-o'-lantern at their home (and the other108 did not). If appropriate, use this information to test if the proportion of all people who went trick-or-treating who also had a pumpkin carved into a jack-o'-lantern attheir home is less than 0.62 at the a= .10 level of significance.A simple random sample of 270 people who went trick-or-treating is selected, and 162 of them also had a pumpkin carved into a jack-o'-lantern at their home (andthe other 108 did not). Is the sample size large enough for the Central Limit TheoremCa. Yes because nã= 232.4and n(1-í) = 168 are both greater than 10a. Yes because 162 is greater than 10Yes because noto = 241.4and n(1-1) = 98.6 are both greater than 10a. Yes because não = 167.4and n(1-π) = 102.6 are both greater than 10ro

john is an inspector at new york. he knows from keeping track of good and substandard clothing items that fur the afternoon shirts 4% if the all clothing made will be substandard. if john checks 260 clothing items completed that shift, what is the probability that he will find more than 5% substandard items? assume all conditions for the central limit theorem are met. A. 0.0500 B. 0.7938 C. 0.2294 D. 0.2062
A simple random sample of 320 people who went trick-or-treating was selected, and it was determined that 64 out of these 320 people received fruit in addition to candy. Is the sample size large enough for the central limit theorem to apply?
The Central Limit Theorem (CLT) says O Samples of size 15 are large enough for the CLT to apply for any populations. O As the sample size increases, the sampling distribution of the mean will get closer and closer to a normal distribution. O Regardless of the sample size, the sampling distribution of the mean is always close to a normal distribution. O Only for symmetric population distributions, the sampling distribution of the mean will get close to a normal distribution as the sample size increases.
Let X1 and X2 be observations of a random sample of size n = 2 from a Cauchy Distribution.Find P(X1 < −1 and 1 < X2)
The Central Limit Theorem is important in statistics because: For a large n, it says the population is approximately normal. For any size sample, it says the sampling distribution of the sample mean is normal. For a large n, it says the sampling distribution of the sample mean is approximately normal, regardless of the population. O For any size sample, it says the sampling distribution of the sample mean is approximately normal. O For any population, it says the sampling distribution of the sample mean is approximately normal, regardless of the sample size. 5 O ♫ LAO AR MacBook Pro 3 P

A study found that 1 out of 200 adult males have green eyes. If a random sample of 400 adult males is obtained, is the sampling of the sample proportion of males that have green eyes approximately normal? A. Yes, the sample size is greater than 10% of the population. B. Yes, the sample was randomly selected C. No, because np < 10 D. No, because nq < 10
Sixty seven percent of the U.S households, or about 85 million families, own a pet, according to the 2019-2020 national pet owners survey conducted by the American pet products association (APPA). A small pet shop opens in your neighborhood and randomly and independently select 800 families to attend the grand opening of the store. Check the conditions of the central limit theorem for this scenario. Calculate the number of failures.
When presented with fingerprints from the same individual, a fingerprint expert will correctly identify the match 94% of the time, Suppose a random sample of 110 was collected and you were asked to find the probability that more than 90% of the fingerprints were correctly idenfied. Which one of the following conditions for the Central Limit Theorem (CLT) is not met? O a. The expected number of "successes" in the sample is too small. O b. The expected number of "failures" in the sample is too small. O,. Relative to the size of the sample, the population is not large enough. O d.A non-random sample was collected.
