Sally is analyzing wheat production. She sampled 700 wheat farmers from across the state. She found a sample mean of 39 bushels per acre, with a standard deviation of 4.5 bushels. Using a 95% confidence interval, what inference can she make? O The yield per acre of wheat farms in the state ranges from 36.32 to 37.35 bushels. O The yield per acre of wheat farms in the state ranges from 38.67 to 39.33 bushels. O The yield per acre of wheat farms in the state ranges from 42.64 to 46.31 bushels. The yield per acre of wheat farms in the state ranges from 43.86 to 49.52 bushels.
Here are the summary statistics for randomly selected weights of newborn girls: n =247, x= 32.2 hg, s= 6.8hg . Construct a confidence interval estimate of the mean. Use 90% confidence level. Are these results very different from the confidence interval 31.0 hg < u < 33.2 hg with only 18 sample values, x= 32.1 hg and s=. 2.7 hg ? What is the confidence interval for the population mean u ? _ hg < u< hg _ (round to one decimal places as needed ? Are the results between the two confidence intervals very different ? a. Yes, because the confidence interval limits are not similar. b. No. because the confidence interval limits are similarc. Yes, because one confidence interval does not contain the mean of the other confidence intervald.
