An incubation period is a time between when you contract a virus and when your symptoms start. Assume that the population of incubation periods for a novel coronavirus has the population standard deviation of 1.6 day(s), also assume that the sample is from a normal population. By surveying randomly selected local hospitals, a researcher was able to obtain the following sample of incubation periods of 19 patients: 7 11 9 3 7 7 9 8 8 8 8 11 9 8 8 7 8 9 8 (Note: The average and the standard deviation of the data are respectively 8.05 day(s) and 1.68 day(s).) At 5% significance level, test the claim that the average incubation period of the novel coronavirus is different from 6 day(s). Procedure: Assumptions: (select everything that applies) Population standard deviation is unknown Simple random sample The number of positive and negative responses are both greater than 10 Sample size is greater than 30 Population standard deviation is known Normal population

Question
An incubation period is a time between when you contract a virus and when your symptoms start. Assume that the population of incubation periods for a novel coronavirus has the population standard deviation of 1.6 day(s), also assume that the sample is from a normal population. By surveying randomly selected local hospitals, a researcher was able to obtain the following sample of incubation periods of 19 patients:
| 7 | 11 | 9 | 3 | 7 |
| 7 | 9 | 8 | 8 | 8 |
| 8 | 11 | 9 | 8 | 8 |
| 7 | 8 | 9 | 8 |
(Note: The average and the standard deviation of the data are respectively 8.05 day(s) and 1.68 day(s).)
At 5% significance level, test the claim that the average incubation period of the novel coronavirus is different from 6 day(s).
Procedure:
Assumptions: (select everything that applies)
- Population standard deviation is unknown
- Simple random sample
- The number of positive and negative responses are both greater than 10
Sample size is greater than 30- Population standard deviation is known
- Normal population
