Abank manager wanted to double-check her claim that recent process improvements have reduced customer wait times to an average of 3.3 minutes, with a standard deviation of 0.9 minutes. to testthis, she randomly sampled 25 customers and recorded their wait times. the average wait time of the customers in the sample was 3.8 minutes. assuming the claim about wait time is true, what is the probability that a random sample of n=25 customers would have a sample mean as large as or greater than 3.8 minutes? what should the manager conclude about her claim?

p(x> or = 3.8) = (round to four decimal places as needed)

what conclusion should the manager draw about her claim of improved service times?

choose one.

a) the manager is accurately estimating wait times

b) the manager is underestimating wait times

c) the manager is overestimating wait times

d) the customers are overestimating wait times.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
