n = 36
μ = 18
σ = 1.8
For 95% confidence and degree of freedom = 36 -1 = 35
t = 2.0301
confidence interval
= μ ± (t * σ / √n )
= 18 ± ( 2.0301 * 1.8 / √36)
= 18 ± 0.60903
= ( 17.39097 , 18.60903 )

a. You measure 43 watermelons' weights, and find they have a mean weight of 48 ounces. Assume the population standard deviation is 2.2 ounces. Based on this, what is the maximal margin of error associated with a 95% confidence interval for the true population mean watermelon weight? Give your answer as a decimal, to two places ± ounces b. You measure 25 watermelons' weights and find they have a mean weight of 44 ounces. Assume the population standard deviation is...

7. You want to estimate the mean weight loss of people one year after using a popular weight-loss (1 point) program being advertised on TV. How many people on that program must be surveyed if we want to be 95% confident that the sample mean weight loss is within 0.25 ib of the true population mean? Assume that the population standard deviation is known to be 10.6 lb. 6907 0 4865 O 84 O6906 3. Given the standard deviation of...

a. Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 343 with 292 successes at a confidence level of 99.8%. M.E.= b. You measure 46 textbooks' weights and find they have a mean weight of 79 ounces. Assume the population standard deviation is 7.5 ounces. Based on this, construct a 90% confidence interval for the true population mean textbook weight. Give your answers as...

10. Fill in the blank. In developing a 96% confidence interval estimate for some normal population mean μ, the population standard deviation σ was 10, The interval estimate was found to be 12.6 ±3.64. Had σ equaled 5, the interval estimate would be 12. Based on a sample of size n 21 drawn from a normal population, the sample mean and sample standard deviation are, respectively, 15.68 and 1.36. We use T-test to test Ho : μ 15 vs H1...

A quality control specialist for a restaurant chain takes a random sample of size 10 to check the amount of soda served in the 16 oz. serving size. The sample mean is 13.20 with a sample standard deviation of 1.51. Assume the underlying population is normally distributed. Find the 95% confidence interval for the true population mean for the amount of soda served.

Question 7: (1 mark for each part) An agronomist wanted to estimate the mean weight of a certain fruit (?) in his farm. He selected a random sample of size ? = 16, and found that the sample mean ?̅ = 55 gm and a sample stranded deviation ? = 3 gm. It is assumed that the population is normal with unknown standard deviation (?). a) Find a point estimate for (?). b) Find a 95% confidence interval for the...
