A research scientist is assessing the effectiveness of a new nasal spray in releasing nasal congestion. Test subjects used the nasal spray and then reported how long it took for their congestion to clear up. The sample of 15 subjects is normally distributed with a mean time of 32.0 minutes with a standard deviation of 2.0 minutes. Answer the following: 1. The mean of a sampling distribution based on this data is [Select ] 2. The standard error of the mean for a sampling distribution based on this data is [Select] 3. The shape of the sampling distribution based on this data will be (Select} v than the original (raw) distribution. 4. For a 90% confidence interval, the margin of error is Select]
