Answer :
Final answer:
To find the probability of a diagnosis occurring between 1.75 and 1.85 days, we can use z-scores and the standard normal distribution.
Explanation:
To find the probability that a diagnosis occurs on average between 1.75 and 1.85 days, we need to standardize the values using the formula z = (x - mean) / standard deviation. The z-scores are calculated as follows:
- z1 = (1.75 - 12.4) / 2.1 = -5.1905
- z2 = (1.85 - 12.4) / 2.1 = -4.5238
Then, we can use a standard normal distribution table or calculator to find the probability between these z-scores.
