To evaluate the effect of a treatment, a sample is obtained and a treatment is administered tothe individuals in the sample. After treatment, the sample mean is found to be X = 14.8 witha standard deviation of a = 4.1. Construct a 95% confidence interval for μ, the populationmean for the treatment group, assuming the sample contains:(a) N = 15 individuals.(b) N = 30 individuals.(c) Comparing your answers for parts (a) and (b), how does the size of the sample influencethe width of your confidence interval for µ?

From the provided information, Population standard deviation (σ) = 4.1 Sample mean (x̄) = 14.8…

Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=21.4. You would like to be 98% confident that your estimate is within 5 of the true population mean. How large of a sample size is required?
A statistics class is estimating the mean height of all female students at their college. They collect a random sample of 42 female students and measure their heights. The mean of the sample is 65.3 inches and the sample standard deviation is 5.4 inches. Find the 90% confidence interval for the mean height of all female students in their school? Assume that the distribution of individual female heights at this school is approximately normal. 1. The t value is 1.3025 2. The standard error has a value of -- 3. The margin of error has a value of 4. Find the 90% confidence interval for the mean height of all female students in their school

The tensile strengths of two types of materials were investigated by collecting 16 samples of each material (totally 32 samples).The sample mean for material 1 was 423.08 (psi), and for material 2 was 424.7 (psi). The samplestandard deviation of the difference in tensile strengths was sD = 2.8 (psi). Is there sufficientevidence to conclude that two types of materials have the same tensile strength? Formulate andtest the appropriate null H0 and alternative hypotheses H1 to verify the claim at level α = 0.01

The average price of a sample of 12 bottles of diet salad dressing taken from different stores is $1.43. The standard deviation is $0.09. The average price of a sample of 16 low-calorie frozen desserts is $1.03. The standard deviation is $0.10. At α = 0.05, is the price of salad dressings significantly higher than the price of frozen desserts?
You would like to construct a 95% confidence interval to estimate the population mean score on a nationwide examination in psychology, and for this purpose we choose a random sample of exam scores. The sample we choose has a mean of 511 and a standard deviation of 71. (a) What is the best point estimate, based on the sample, to use for the population mean? X ? (b) For each of the following sampling scenarios, determine which distribution should be used to calculate the critical value for the 95% confidence interval for the population mean. (In the table, Z refers to a standard normal distribution, and t refers to a t distribution.)
In a simulation project, the time (in minutes) between arrivals of customers to a post office is to be modelled. The team collected the arrival data of 200 customers and arranged it to perform a x² goodness- of-fit test in the table below. They checked the histogram of the data and thought that the distribution should be Normal with the estimated mean value T = 124 min and standard deviation s = 15.50 min.
