3. A machine that produces buckles for luxury designer bags, is known to produce 3% defective buckles. Following a major breakdown of the machine, extensive repair work is carried out which may result in a change in the percentage of defective buckles produced. To investigate this possibility, a random sample of 200 buckles is taken and 12 defective 8 UTM & UTM 8 UTM 8 UTM 8 UTM 3 UTM 8 UT buckles were found. Is there sufficient evidence to indicate that the percentage of defective buckles produced has changed following the repair work? Test at 1% level of significance level. Assume that the observations are from a normal distribution. Activate Windows Go to Settings to activat
