The medical team believes it can demonstrate that factor x is raised in the bloodstream by an average of more than 1.5. in what follows let µ1 denote the average of factor x with the with the new medication and let µ2 denote the average level of factor x with the placebo. the team establishes a 1% level of significance. the team thinks that it can establish the alternative hypothesis ha: − > 1.50.referring to increase, find the critical value. a) -4.541 b) 4.541 c) ±5.841 d) -1.638 e) 2.998

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

the bolded word " farsighted" could be replaced with visionary.
