please i need help chapter 8 question 17,22 to problem solve thanks!

2. What is the probability . ``^ score less than * = }! ?! Ilike results obtained ing study are shown in the following table . bo. What is the probability of sex_ _ _ sample of ~ = 4 scores with a mean less than $ =_ 51 ? Self-Reported Level of Pain C . What is the probability of selecting a sample of Mean ~ = 36 scores with a mean less than M = 51 ? Tai Chi course 3. 7 16 . A population has a mean of M = 30 and a standard No Tai Chi course deviation of o = 8 7.6 2 . If the population distribution is normal , what is the probability of obtaining a sample mean greater* 2 . Construct a bar graph that incorporates all of the than M = 32 for a sample of n = 4 ? information in the table . b . If the population distribution is positively skewed , b. Looking at your graph , do you think that particing what is the probability of obtaining a sample mean tion in the Tai Chi course reduces arthritis pain ? greater than M = 32 for a sample of n = 4 ? 21 . A normal distribution has a mean of 1 = 60 and a C . If the population distribution is normal , what is standard deviation of ` = 18 . For each of the follow. the probability of obtaining a sample mean greater ing samples , compute the z- score for the sample mean than M = 32 for a sample of n = 64 ?" and determine whether the sample mean is a typical . d . If the population distribution is positively skewed , representative value or an extreme value for a sample what is the probability of obtaining a sample mean of this size . greater than M = 32 for a sample of n = 64 ? a . M = 67 forn = 4 scores 17 . \\ For random samples of size ~ = 25 selected from a nor - b. M = 67 forn = 36 scores mal distribution with a mean of mean of M = 50 and a 22 . ) A random sample is obtained from a normal popular standard deviation of o = 20 , find each of the following : tion with a mean of M = 95 and a standard deviation 2 . The range of sample means that defines the middle 95% of the distribution of sample means . of o = 40 . The sample mean is M = 86 . b . The range of sample means that defines the middle 2 . Is this a representative sample mean or an extreme 99 % of the distribution of sample means . value for a sample of ~ = 16 scores ? b . Is this a representative sample mean or an extreme 8 . The distribution ages for students at the state college value for a sample of n = 100 scores ? is positively skewed with a mean of M = 21.5 and a standard deviation of o = 3 .` 23 . A normal distribution has a mean of M = 65 and a 2 . What is the standard deviation of o = 20. For p! fallow
