requires a large sample. For each of the following combinations of n and p ^ , indicate whether the sample size is large enough for use of this interval to be appropriate.

  1. a. n = 50 and p ^ = 0.30
  2. b. n = 50 and p ^ = 0.05
  3. c. n = 15 and p ^ = 0.45
  4. d. n = 100 and p ^ = 0.01

An independent random sample is selected from an approximately normal population with an unknown standard deviation. Find the p-value for the given sample size and test statistic. Also determine if the null hypothesis would be rejected at α = 0.05. For each the given set of hypotheses, sample size and the T-statistic,find the p-value, draw a t-curve and shade the region of which the area the p-value indicates. As it’s notpossible to find the precise P-values using a t-table, it suffices to give a range. (a) HA : μ 6= 0.5, n = 26, T = 2.6(b) HA : μ < 3, n = 18, T = −2.2(c) HA : μ < 3, n = 18, T = 2.2
The thickness (in millimeters) of the coating applied to hard drives is one characteristic that determines the usefulness of the product. When no unusual circumstances are present, the thickness (x) has a normal distribution with a mean of 4 mm and a standard deviation of 0.02 mm. Suppose that the process will be monitored by selecting a random sample of 25 drives from each shift's production and determining x,  the mean coating thickness for the sample. Describe the sampling distribution of x for a random sample of size 25. The distribution of x is  normal with mean ? mm and standard deviation ? mm.   When no unusual circumstances are present, we expect x to be within 3? x of 4 mm, the desired value. An x value farther from 4 mm than 3? x is interpreted as an indication of a problem that needs attention. Calculate 4 ± 3? x. 4 − 3? x= ? mm 4 + 3? x= ? mm   Referring to part (b), what is the probability that a sample mean will be outside  4 ± 3? x  just by chance (that is, when…
The amounts of time employees of a telecommunications company have worked for the company are normally distributed with a mean of 5.1 years and a standard deviation of 2.0 years. Random samples of size 19 are drawn from the population and the mean of each sample is determined. Use the Central Limit Theorem to find the mean and standard error of the mean of the indicated sampling distribution.

  • The government of an impoverished country reports the mean age at death among those who have survived to adulthood as 66.2 years. A relief agency examines 30 randomly selected deaths and obtains a mean of 62.3 years with standard deviation 8.1 years.

    The thickness (in millimeters) of the coating applied to hard drives is one characteristic that determines the usefulness of the product. When no unusual circumstances are present, the thickness (x) has a normal distribution with a mean of 3 mm and a standard deviation of 0.05 mm.

    Suppose the incidence rate of myocardial infarction (MI) was 5 per 1000 among 45- to 54-year old men in 2000. To look at changes in incidence rate over time, 5000 men in this age group were followed for 1 year starting in 2010. Fifteen new cases of MI were found. 1.) Compute the test statistic. Must show all work. 2.) Draw the region with appropriate labels that shows the p-value.
