Answer:  Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of times the spinner spun = 75

Outcomes     Frequency

A                          20

B                           11

C                           14

D                           30

We need to find the experimental probability of spinning an "A" :

so, Probability of spinning an A is given by

Probability of getting an A is 0.27.

Hence, Option 'c' is correct

storchak [24]

Answer:

$149.09

Step-by-step explanation:

56.75-14.10=42.65

42.65+41.50=84.15

84.15-11.03=73.12

73.12-7.25=65.87

65.87+83.22=149.09

suppose a consumer advocacy group would like to conduct a survey to find the proportion p of consumers who bought the newest gen
Zepler [3.9K]

The size of the sample they should take to estimate p with a 2% margin of error and 90% confidence is n = 1691.

In statistics, the margin of error is just the degree of a significant error in the outcomes of random sample surveys.

The formula of margin error is, E = z√((p-vector)(1 - (p-vector)) ÷ n)

E = 2% = 0.02

Confidence level = 90%

Now, the proportion is not given so adopt nominal (p-vector) = 0.05

The critical value at CL of 90% is 1.645.

Thus, making n the subject,

n = z²(((p-vector) × (1 - (p-vector))) ÷ E²)

n = 1.645²((0.5 × 0.5) ÷ 0.02²)

n = 1691.266

n ≈ 1691
