At a large company banquet for several thousand employees and their families, many of the attendees became ill the next day. The

yan [13]

Answer:

a. Yes. This provides convincing evidence that the true proportion of all attendees who ate the fish that got sick (80%) is more than the true proportion of all attendees who did not eat the fish that got sick.

b. The mistake here would have been the rejection of the Doctor's theory or hypothesis to the effect that more attendees who ate the fish got sick than those who did not eat the fish. This is a Type 1 error. A Type 1 error occurs when a null hypothesis is rejected when it is true. On the other hand, a Type II error occurs when the null hypothesis is accepted when it should be rejected. While a Type I error is equivalent to a false positive, a Type II error is equivalent to a false negative.

Step-by-step explanation:

Total number of attendees who ordered fish = 1,000

Sample size of the attendees who ate fish = 80

Number of attendees who ate the fish and got sick = 64 (80% or 64/80)

Sample size of attendees who did not eat fish = 60

Number of attendees who did not eat fish and got sick = 39 (65% or 39/60)

A boat is 400 feet away from one dock and 500 feet away from the another dock. the angle between the paths is 45°. what is the a

FinnZ [79.3K]

Answer:

The approximate distance between the docks is 357 feet

Step-by-step explanation:

Let the distance between docks be d.

This is the opposite side to 45° angle of triangle with other sides 400 ft and 500 ft.

Use the law of cosines to find the value of d:

$d = \sqrt{400^2+500^2-2*400*500*cos45} =357$ (rounded)

Answer:

P [ β / Def] = 0,6521 or 65,21 %

Step-by-step explanation:

Tree diagram:

0,20 (α) Defective 0,02

0,50 (β) defective 0,06

0,30 (γ) defective 0,04

According to Baye´s Theorem

P [ A/B] = P[A] * P [ B/A] / P[B]

if we call

β = A and Defective = B then P[β] = P[A] and P[Defective] = P[B]

we get :

P [ β / Def] = P[β] * P [ def./β] / P[def]

Then

P[β] = 0,5

P[def/β] = 0,06

P [Defective] = 0,02* 0,2 + 0,06*0,5 + 0,04*0,3

P [Defective] = 0,004 + 0,03 + 0,012

P [Defective] = 0,046

P [ β / Def] = 0,5 * 0,06 / 0,046

P [ β / Def] = 0,6521 or 65,21 %
