Crosses of mice will produce either gray, brown, or albino offspring. Mendel's model predicts that the probability of a gray off

spring is 9/16 ; the probability of a brown offspring is 3/16 ; and the probability of an albino offspring is 4/16. a. An experiment to assess the validity of Mendel's theory produces the following data: 35 gray offspring; 19 brown offspring; and 24 albino offspring. Test H0: p1=9/16, p2=3/16, p3=4/16 vs H1: not H0 (i) at α=0.05, (ii) at α=0.10.

Answer:

The mice in the sample are as per proportion given

Step-by-step explanation:

Given that crosses of mice will produce either gray, brown, or albino offspring.

Mendel's model predicts that the probability of a gray offspring is 9/16 ; the probability of a brown offspring is 3/16 ; and the probability of an albino offspring is 4/16.

H_0: Samples have proportion as given

H_a: atleast one does not have the proportion

(Two tailed chi square test)

Sample size n =78

Contingency and chi square table are:

Grey Brown Albino Total

   

Prob   9/16   3/16   1/4  1      

Observed O 35       19       24       78      

Expected E 43  7/8  14  5/8  19  1/2  78      

Chi square 1 66/83 1 21/68 1  1/26 4  1/7  

   

p value   1/8    

Since p value >0.10, we accept null hypothesis

The mice in the sample are as per proportion given

A student fond the slope of a line that passes through the points (-8,-6) and (2,-3) to be 3/10. what mistake did she make?
goldfiish [28.3K]
Simple ....

we know to find slope is (y1-y2)/(x1-x2)

if we plug in what we know......

(-8,-6),(2,-3)

(-6--3)/(-8-2)

it turns into...

(-6++3)/(-8+-2)

(-3)/(-10)= 3/10

Thus, your answer is that she made no mistake. (C)

The parents have to give 65 dollars for their children to be under care till 6 o'clock. AFter 6 o'clock, they had to pay 1.50 dollars for one minute. This parent gives a total of 78.50 dollar for that day. So, the equation is :

1.50m=13.50

m= 9
