Find the mode for the following group of data items. If there is no mode, so state. \( 2.9,5.1,6.3,4,5.5,5.5,4.5,6,4.9,3.8,3.8 \) Select the correct choice below and, if necessary, fill in the answer box within your choice. A. The mode(s) is/are \( \square \). (Use a Somma to separate answers as needed.) B. There is no mode.

ou are conducting a study to see if the accuracy rate for fingerprint identification is significantly different rom 0.19 . Thus you are performing a two-tailed test. Your sample data produce the test statistic \( =1.358 \). Find the p-value accurate to 4 decimal places.

Progress saved Done Question 12 You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 0.73. Thus you are performing a left-tailed test. Your sample data produce the test statistic \( z=-1.83 \). Find the p-value accurate to 4 decimal places. p-value \( = \) Submit Question

You are conducting a study to see if the proportion of voters who prefer Candidate \( A \) is significantly more than 0.13 . Thus you are performing a right-tailed test. Your sample data produce the test statistic \( z=1.354 \). Find the p-value accurate to 4 decimal places. \( p \)-value \( =\square \)

You are conducting a study to see if the proportion of women over 40 who regularly have mammograms is significantly different from 0.4 . Thus you are performing a two-tailed test. Your sample data produce the test statistic \( z=-1.346 \). Find the \( p \)-value accurate to 4 decimal places. p-value \( = \) Submit Question

examined is significantly less than 0.77 . Thus you are performing a left-tailed test. Your sample data produce the test statistic \( z=-2.924 \). Find the \( p \)-value accurate to 4 decimal places. \( p \)-value \( = \)
