The proportion of field mice weighing more than 33 grams in the distribution will be about 0.2275

  • Mean, μ = 25 grams
  • Standard deviation, σ = 4 grams
  • Score, X = 33 grams

We need to calculate the P(Z > Zscore)

Recall :

Zscore = (X - μ) ÷ σ

For X > 33 :

Zscore = (33 - 25) ÷ 4 = 2

Therefore, the probability would be expressed as :

P(Z > 2) = 1 - P(Z < 2)

From the normal distribution table :

P(Z < 2) = 0.97725

Therefore,

P(Z > 2) = 1 - 0.97725 = 0.02275

padilas [110]

Mr Reams uses 10 cups of paint to fill the small dishes, therefore, the amount of paints left in the bowl is 2 cups.

<h3>How to convert ounces to cups?</h3>

He mixes 12 cups of paints in a large bowl.

He uses the paint to fill 40 small dishes with 2 fluid ounces of paint each.

1 small dish = 2 fluid ounces

40 small dishes = 80 fluid ounces

Therefore,

1 fluid 0unces = 0.125 cups

80 fluid ounces = ?

cross multiply

amount of paint filled = 80 × 0.125 = 10 cups

Therefore, the amount of cups pf paint Mr Reams have left in the bowl is 12 cups - 10 cups = 2 cups.

For a laboratory assignment if the equipment is working the density function of the observed outcome
vivado [14]

Based the density function of the observed outcome, the probability P(x\leq \frac{1}{3} ) is equal to 0.1388.

<h3>What is a density function?</h3>

A density function can be defined as a type of function which is used to represent the density of a continuous random variable that lies within a specific range.

Given the following density function:

f(x)=\left \{ {{2(1-x),\;0 < x < 1} \atop {0,\; otherwise}} \right.

Next, we would calculate P(x\leq \frac{1}{3} );

P(x\leq \frac{1}{3} )=\int\limits^\frac{1}{3} _0 {f(x)} \, dx \\\\P(x\leq \frac{1}{3} )=2 \int\limits^\frac{1}{3} _0 {(1-x)} \, dx \\\\P(x\leq \frac{1}{3} )=2|x-\frac{x^2}{2} |\limits^\frac{1}{3} _0\\\\P(x\leq \frac{1}{3} )=2[\frac{1}{3} -\frac{1}{2} (\frac{1}{3})^2]\\\\P(x\leq \frac{1}{3} )=2[\frac{1}{3} -\frac{1}{18}]\\\\P(x\leq \frac{1}{3} )=0.1388
