Step-by-step explanation:
mean when 82 is present
=<u>8</u><u>2</u><u>+</u><u>4</u><u>4</u><u>+</u><u>2</u><u>7</u><u>+</u><u>9</u><u>6</u><u>+</u><u>6</u><u>9</u><u>+</u><u>8</u><u>0</u><u>+</u><u>7</u><u>5</u><u>+</u><u>8</u><u>3</u><u>+</u><u>5</u><u>6</u><u>+</u><u>9</u><u>8</u>=<u>7</u><u>1</u><u>0</u>
10 10
= 71
mean when 42 is present
=<u>4</u><u>2+44+27+96+69+80+75+83+56+98</u>=<u>6</u><u>7</u><u>0</u>
10 10
=67
therefore the mean decreases with
= 71 - 67 = 4
