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)

Makovka662 [10]

Answer:

i. T = Y + 1

ii. today's closing price 33

Step-by-step explanation:

Given that: Carlie's stock rose by 1 points in trading today.

Let Y represent yesterday's stock price at closing

Let T represent today's stock price at closing

=> formula that correctly relates Y and T is:

T = Y + 1

ii) If yesterday's closing price was 32 what was today's closing price?

today's closing price = yesterday's closing price + 1

<=> T = Y + 1

<=> T = 32 + 1 = 33

Femi keeps track of a number of gallons of gasoline he uses for each of several trips. Part A: Complete the table. The vehicle c

Viktor [21]

The table is attached.

A) The gasoline consume grows as the distance traveled increases. This means that the two quantities are directly proportional.

Therefore, the proportionality constant is given by:
k = gasoline / distance
   = 2 / 40
   = 0.05
We could have used also:
k = 3 / 60
   = 0.05

In order to find the gasoline consumed, you need to multiply the distance by the proportionality constant:
30 × 0.05 = 1.5
55 × 0.05 = 2.75

In order to find the distance traveled, you need to divide the gasoline consumed by the proportionality constant:
3.5 ÷ 0.05 = 70

B) The function of the proportionality found is:
y = 0.05·x
where:
x = distance
y = gasoline

Therefore:
y = 0.05·110 = 5.5

Femi for a trip of 110 miles expects to use 5.5 gallons of gasoline.
