Jensen has a basket containing oranges apples and pears he picks a piece of fruit from the basket 40 times, replacing the food b

efore each draw from these 40 trials Jensen estimates that the probability of picking an orange is 0.25 the probability of picking an apple is 0.3 and the probability of picking a pair is 0.45 how many times did Jensen pick an apple doing the £.40 trials

In this question, we're trying to find how many apples Jenson picked from the basket.

Lets gather information that can help us.

Important information:

• Picked a fruit from a basket 40 times Probability of picking an apple is 0.3

With the information above, we can solve the question.

We know that he picked up a fruit 40 times, but we need to find how many apples he picked up during the 40 times.

The probability of picking an apple is 0.3, which is equivalent to 30%

This means that 30% of the 40 times he picked an apple.

We would multiply 40 by 0.3 to get our answer.

<h2>40* 0.3 =12</h2>

This means that Jenson picked 12 apples.

13. Describe the system by substitution:<br> y=x-7<br> 2x - y = 3
torisob [31]

Answer:

x = y + 7 \\  \\ x =  \frac{3 + y}{2}  \: or \: y = 2x - 3

Step-by-step explanation:

1. \: 2x = 3 + y \\ 2. \: x =  \frac{3 + y}{2}  \: or \: y = 2x - 3 \\  \\ 1. \: y + 7 = x \\ 2. \: x = y + 7

A marketing research company desires to know the mean consumption of milk per week among people over age 32. A sample of 440 peo
Softa [21]

Answer:

The 98% confidence interval for the mean consumption of milk among people over age 32 is between 3.3 and 3.5 liters.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.98}{2} = 0.01

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.01 = 0.99, so Z = 2.327.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 2.327\frac{0.8}{\sqrt{440}} = 0.1

The lower end of the interval is the sample mean subtracted by M. So it is 3.4 - 0.1 = 3.3 liters

The upper end of the interval is the sample mean added to M. So it is 3.4 + 0.1 = 3.5 liters

The 98% confidence interval for the mean consumption of milk among people over age 32 is between 3.3 and 3.5 liters.
