Question
correct estion 1 of 10, Step 1 of 1 The diameters of bolts produced in a machine shop are normally distributed with a mean of 5.7 millimeters and diameters that separate the top 3 to the nearest hundredth, if necessary. a standard deviation of 0.08 millimeters. Find the two % and the bottom 3 % . These diameters could serve as limits used to identify which bolts should be rejected Round your answer Tables Keypad Answer If you would like to look up the value in a table, select the table you want to view then either cick the cell at the intersection of the row and column or use the arro v keys to find the appropr ate cell in the table and select it using the Space key. Note: Selecting a cell will return the value associated with the column and row headers for that cell millimeters and millimeters Normal Table 0 to z Normal Table-to-1 Normal Tableto Submit AnswerExplanation / Answer
Result:
Z value for top 3% is 1.881 and bottom 3% is -1.881
Lower value = mean+z*sd = 5.7-1.881*0.08 = 5.54952
upper value = mean+z*sd = 5.7+1.881*0.08 = 5.85048
The values are 5.50 and 5.85 ( two decimals)
