The Town of Hertfordshire clerk knows that 23% of dogs in the town have completed emotional support training. Hertfordshire plans on showcasing a simple random sample of its dogs in a show. Depending on which dogs are chosen, the proportion of emotional support trained dogs may vary. In a sample of 50 dogs, what is the probability that less than 6% of the dogs are emotional support trained?

Give your answer to four decimal places.

0.0021 is  the probability that less than 6% of the dogs are emotional support trained.

Step-by-step explanation:

We are given the following in the question:

p = 23% = 0.23

Sample size, n = 50

Formula:

Putting the values, we get,

Thus, we have to evaluate

P( z < -2.8564)

Calculating the value from standard normal z-table,

Thus, 0.0021 is  the probability that less than 6% of the dogs are emotional support trained.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
