Seed are often treated with fungicides to protect them in poor draining, wet environments. A small-scale trial, involving five t

reated and five untreated seeds, was conducted prior to a large-scale experiment to explore how much fungicide to apply. The seeds were planted in wet soil, and the number of emerging plants were counted. If the solution was not effective and four plants actually sprouted, what is the probability that : a) all four plants emerged from treated seeds? b) three or fewer emerged from treated seeds? c) at least one emerged from untreated seeds?

Answer:

MAD = 2

Step-by-step explanation:

<u><em>First We'll find the mean of data</em></u>

Mean = \frac{20}{5}

Mean = 4

<u><em>Then, we'll find absolute deviation</em></u>

=> |4-3| = 1

=> |4-2| = 2

=> |4-1| = 3

=> |4-1| = 3

=> |4-3| = 1

<em><u>Now, taking the mean of these absolute deviations:</u></em>

MAD = \frac{1+3+3+2+1}{5}

MAD = \frac{10}{5}

MAD = 2

Oksi-84 [34.3K]

Answer:

D) {1, 2, 3}

Step-by-step explanation:

Simply solve for m given our equation:

<em>11 = 3.50 + 2.50m</em>

Start by subtracting 3.50 on both sides:

<em>7.5 = 2.50m</em>

Next, divide by 2.50 on both sides to obtain our value for m:

<em>3 = m</em>

Now since we're looking for a complete set of values, we have to consider all values that are 3 and below for m. This makes D) our answer
