The mean cost of a five pound bag of shrimp is 40 dollars with a standard deviation of 7 dollars. If a sample of 51 bags of shri

eimsori [14]

Answer:

$P(|\bar{x}-40| > 0.6)=0.5404$

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 40 dollars

Standard Deviation, σ = 7 dollars

Sample size,n = 51

We are given that the distribution of cost of shrimp is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Standard error due to sampling =

$=\dfrac{\sigma}{\sqrt{n}} = \dfrac{7}{\sqrt{51}} = 0.9801$

P(sample mean would differ by true mean by more than 0.6)

$P(|\bar{x}-40| > 0.6)\\\Rightarrow = 1-P(39.4$

$P(39.4 \leq x \leq 40.6) \\\\= P(\displaystyle\frac{39.4 - 40}{0.9801} \leq z \leq \displaystyle\frac{40.6-40}{0.9801})\\\\ = P(-0.6121 \leq z \leq 0.6121)\\= P(z \leq 0.6121) - P(z < -0.6121)\\= 0.7298 - 0.2702 =0.4596$

$P(|\bar{x}|-40 > 0.6)\\= 1-0.4596=0.5404$

0.5404 is the required probability.

Here is an array of ten integers 6 4 0 3 9 8 1 7 2 5

garik1379 [7]

Answer:

$[4,0,3,1,2,5]$ and $[6,9,8,7]$

Step-by-step explanation:

GIVEN: an array of ten integers $6,4,0,3,9,8,1,7,2,5$ .

TO FIND: If we partition this array using Quick sort's partition function and using $5$ for the pivot. List the elements of the resulting array after the partition finishes.

SOLUTION:

quick sort is a divide and conquer algorithm in which an array is partitioned into sub-arrays about an pivot element by checking whether elements are greater than pivot or and then sub arrays are sorted recursively.

Here $5$ is the pivot element.

two arrays will be created, in first array element less than or equal to pivot element are stored in other elements greater than pivot element are stored.

Starting from first element of array

elements in first array will be $=[4,0,3,1,2,5]$

elements in second array will be $=[6,9,8,7]$

Hence the resulting array after the partition finishes are $[4,0,3,1,2,5]$ and $[6,9,8,7]$

For the most recent seven years, the U.S. Department of Education reported the following number of bachelor's degrees awarded in

bixtya [17]

Answer: 8327

Step-by-step explanation:

The arithmetic mean of a data is given by :_

$\dfrac{\text{Sum of observations}}{\text{Number of observations}}\\\\=$

Given : For the most recent seven years, the U.S. Department of Education reported the following number of bachelor's degrees awarded in computer science: 4,033; 5,652; 6,407; 7,201; 8,719; 11,154; 15,121.

Then, the annual arithmetic mean number of degrees awarded will be :-

$\dfrac{4033+5652+6407+7201+8719+11154+15121}{}\\\\=\dfrac{58287}{7}\\\\=8326.71428571\approx8327$

Hence, the annual arithmetic mean number of degrees awarded = 8327
