A. Reject the alternative hypothesis
B. Reject the null hypothesis
C. Fail to reject the null hypothesis
D. Type I error

0.05 and all smaller a
B. fail to reject the null hypothesis at a =
= 0.05 and all smaller a

- A 95% confidence interval for the difference in proportions of rotted fruit between Orchard A and Orchard B is (0.03, 0.11). What does this mean? X Previous C 95% of the fruit at Orchard A and B are between 3% and 11% rotted. We are 95% confident that the difference in the percentages of rotted fruit at these orchards is between 3 and 11 percentage points. The percentage of rotted fruit at Orchard B is between 3 and 11 percentage points higher than Orchard A. 4 r We are 95% confident that the Orchard A has between 3% and 11% rotted fruit. f 5 % 5 t g Oll A 6 b y h & 7 n O u j 8 m i k ( 9 V O alt 1 e A ctrl [ Next G backspac }arrow_forwardn=10 b = 0.50 sb = 0.02 α=0.05 find the confidence interval for β.arrow_forwardA sample of 260 observations selected from a population produced a sample proportion equal to 0.85. a.

- Let μ denote some population mean of interest and suppose a 95% confidence interval for μ is calculated to be (0.63, 0.73) and a 99% confidence interval for μ is calculated to be (0.61,0.75).
