**Question:**Determine the positive z-score for a 94% confidence interval.**Input Field:**- Positive z = _______ [three decimal accuracy]**Description:**This question requires finding the z-score that corresponds to a 94% confidence level. Note that the result should be accurate to three decimal places.To solve this, recall that the confidence level indicates the probability that the true parameter lies within the specified interval around the sampled data. For a 94% confidence interval, a certain portion of the normal distribution remains in the tails, and the z-score can be found using statistical tables or software tools designed for normal distribution calculations.**Submit Question**: [Button available to submit the response]
