Given the following observed and expected data (total of 1000), using chi-squared calculate a p-value that corresponds with this data: Phenotype Observed Expected
cinnabar, vestigial 384 390
roof 408 390
cinnabar, roof, vestigial 63 70
Wild type 72 70
vestigial 32 35
cinnabar, roof 34 35
roof, vestigial 4 5
cinnabar 3 5

a. 025> p> 0.1
b. 0.9 > p >0.75
c. 0.05 > p
d. 0.75 > p>0.5
e. 0.95 >p >0.9

The answer is ""

Step-by-step explanation:

Eight phenotypes were present.  

Df is provided also by a number of phenotypes -1 The degree of freedom

For p-value 0,9, Chi-square is 2.83;

The p-value of 0.75 is 4.5. Chi-square

Chi-sqaure value is observed at 2.965.

That means 0.90>p-value>0.75.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
