• Question 112:

  Which of the following is the correct test statistic to use for a paired-sample t test?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

  ---

  Explanation

  The correct test statistic for a paired-sample t test is used when comparing the means of two related groups.

  The formula for the paired-sample t test is:

  t=dsd/nt = \frac{\bar{d}}{s_d / \sqrt{n}}t=sd/nd

  Where:

  d\bar{d}d is the mean of the differences between the paired observations.

  sds_dsd is the standard deviation of the differences.

  nnn is the number of pairs.

  II - Magnetic particle.

  III - Pulse echo.

  IV - Eddy current.

  A. I,II and IV only
  B. I and III only
  C. III and IV only
  D. I and IV only
  C. III and IV only

  Explanation

• Question 114:

  In nonparametric statistics:

  I - No assumptions are made concerning the distribution from which the samples are taken.

  II - The parameters of the distribution do not relate to the parameters of the sample.

  III - The sample and the distribution must have no parameters in common.

  A. I only
  B. II only
  C. III only
  D. II and III only
  A. I only

• Question 119:

  The table below shows the results of inspecting 3,752 items. On the basis of this information, a Pareto chart would show what cumulative percent of nonconformities by the end of the third operation?

  Order of Operation Number of Nonconforming ItemsPercent of Nonconforming Items Percent of Nonconformities

  1-3729.9%55.0%

  2nd1564.2%23.3%

  3 rd782.1%11.7%

  4*501.3%7.2%

  5th200.5%2.8%

  A. 16.2%
  B. 21.7%
  C. 78.3%
  D. 90.0%
  C. 78.3%

  ---

  Explanation

  To determine the cumulative percent of nonconformities by the end of the third operation using the given data, we sum the percent of nonconformities for the first three operations:

  1st operation: 55.0%

  2nd operation: 23.3%

  3rd operation: 11.7%

  Cumulative percent of nonconformities by the end of the third operation = 55.0% + 23.3% + 11.7% = 90.0% Hence, the correct answer is 90.0%.

• Question 120:

  Which of the following activities is a critical component of the closing meeting of an external audit?

  A. Determining appropriate corrective actions to take
  B. Establishing the date for a follow-up audit
  C. Distributing the final audit report
  D. Providing an explanation of the findings
  D. Providing an explanation of the findings

  ---

  Explanation

  During the closing meeting of an external audit, a critical component is providing an explanation of the findings to ensure that all parties understand the audit results. This step is essential for clarity and sets the stage for discussing potential corrective actions and follow-up activities.

  "The ISO 19011:2018 Guidelines for Auditing Management Systems," which outlines the key components of audit closing meetings.
