Amanufacturer of small appliances purchases plastic handles for coffeepots from an outside vendor. if a handle is cracked, it is considered defective and must be discarded. a large shipment of plastic handles is received. the proportion of defective handles p is of interest. how many handles from the shipment should be inspected to estimate p to within 0.09 with 95% confidence?

119

Step-by-step explanation:

Since the prior estimate of population proportion of defective handles  (p) is unknown , so we take p= 0.5

Given : Margin of error : E=0.09

Critical value for 95% confidence interval :

Required sample size :-

Hence, the minimum sample size required = 119

i.e. 119 handles from the shipment should be inspected.

∠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.
