An employee is asked to calculate the chi-square value, for company data set for which observed frequency is 9.5 and expected frequency is 19. What will be the Chi-Square value

X² =4.75

Step-by-step explanation:

The formula for calculating the chi square value is expressed as

X² = [ (O - E)²/ E ].

O is the observed frequency

E is the expected frequency

Given

O = 9.5

E = 19

Substitute into the formula:

X² = (9.5-19)²/19

X² = 9.5²/19

X² = 90.25/19

X² = 4.75

Hence the chi square value will be 4.75

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
