Answer:
Null hypothesis:
Alternative hypothesis:
Since the p value is very low compared to the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true percent of people with type A of blood is significantly different from 0.4 or 40%
Step-by-step explanation:
Information given
n=144 represent the random sample taken
X=81 represent the number of people with type A blood
estimated proportion of people with type A blood
is the value that we want to verify
represent the significance level
z would represent the statistic
![p_v{/tex} represent the p value Hypothesis to testWe want to test if the percentage of the population having type A blood is different from 40%.: Null hypothesis:[tex]p=0.4](https://tex.z-dn.net/?f=p_v%7B%2Ftex%7D%20represent%20the%20p%20value%20%3C%2Fp%3E%3Cp%3E%3Cstrong%3EHypothesis%20to%20test%3C%2Fstrong%3E%3C%2Fp%3E%3Cp%3EWe%20want%20to%20test%20if%20the%20percentage%20of%20the%20population%20having%20type%20A%20blood%20is%20different%20from%2040%25.%3A%20%20%3C%2Fp%3E%3Cp%3ENull%20hypothesis%3A%5Btex%5Dp%3D0.4)
Alternative hypothesis:
the statistic is given by:
(1)
Replacing the info given we got:
Now we can calculate the p value with this probability taking in count the alternative hypothesis:
Since the p value is very low compared to the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true percent of people with type A of blood is significantly different from 0.4 or 40%
There are several different equations that can be used to find missing sides, these can be trigonometric functions or the distance formula. The trigonometric functions consist of sine (opposite/hypotenuse), cosine (adjacent/hypotenuse), and tangent (opposite/adjacent. The adjacent side is represented by the side next to the given angle measure, the opposite is the side that is connected to adjacent side and across from the given angle, and the hypotenuse is the diagonal that connects the opposite side to the given angle- most notable because its line isn't straight like the other sides.
The distance formula is used to find the measurement of missing side lengths in all quadrilaterals, and it's: D = sqrt(x2 - x1)^2 + (y2 - y1)^2 where x are the x-coordinates of two given points and y are the y-coordinates of the same two given points.
Answer:
total number of parts of a 2:5 ratio are 7 as 2+5 = 7
let us assume are number to be 49
the first part will be 49/7 × 2 = 14
the second part will be 49/7 × 5 = 35
Answer:
Yes
Step-by-step explanation:
8/10 can be simplified to become 3/4
Answer:
Step-by-step explanation:
In the table, you have an x column and a y column. To find values in the table, you choose your values of x and plug them in as your values of x in the equation, solving for y.
