Points: 0 of 6 Save Assume that the sample is a simple random sample obtained from a normally distributed population of IQ scores of statistics professors. Use the table below to find the minimum sample size needed to be 95% confident that the sample standard deviation s is within 40% of o. Is this sample size practical? To be 95% confident that s is within 1% 10% 20% 30% 40% 50% of the value of o, the sample size n should be at least 19,205 768 192 18 21 12 To be 99% confident that s is within 1% 5% 10% 30% 40% 50% of the value of o, the sample size 14 n should be at least 33,218 1,336 336 85 BE 22 The minimum sample size needed is Clear all Check answer Get more help - Media View an example 10:17 PM Help me solve this 30 0 F ~ 0 ( 1/29/2022 O Type here to search BELL F10 FO F7 @ W M N Caps Lock Curl X
