In a survey of 2264 adults, 729 say they believe in ufos. construct a 95 confidence interval for the population proportion of ad
Andreyy89

90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the giver confidence interval [ 0.3026, 0.3348 ].

Here, we have given:

Number of adults (n) = 2272

Number of adults who believe in UFO (x) = 724

Sample proportion (p) = x/n

p = 724 / 2272

p = 0.3187

now, let q = 1 - p

q = 1 - 0.3187

q = 0.6813

Confidence level → 90%

The 90% confidence interval for population proportion is

[ p - 1.645\frac{\sqrt{pq} }{\sqrt{n}} ,p + 1.645\frac{\sqrt{pq} }{\sqrt{n}} ]

where 1.645 is Zac value at 90% confidence level.

p - 1.645\frac{\sqrt{pq} }{\sqrt{n}}  = 0.3187 - 0.0161 = 0.3026

p + 1.645\frac{\sqrt{pq} }{\sqrt{n}} = 0.3187 + 0.0161 = 0.3348

90% confidence interval for the population proportion is

[ 0.3026, 0.3348 ]

Hence, With 90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the giver confidence interval [ 0.3026, 0.3348 ]

Nuetrik [128]

Complete question:

what is the answer to 22 +10x = 0

Answer:

the value of x is -2.2

Step-by-step explanation:

Given;

22 +10x = 0

collect like terms

10x = 0 - 22

10x = -22

divide both sides by 10

\frac{10x}{10} = \frac{-22}{10} \\\\x = -2.2

Therefore, the value of x is -2.2

A clown bought 6 bags of round balloons with 24 balloons in each bag.The clown also bought 3 bags of long balloons with 36 ballo
Ierofanga [76]
6 bags × 24 balloons = the amount of round balloons
6× 24 = 144
3 bags × 36 balloons = the amount of long balloons
3 ×36=108

108 long balloons - 144 round balloons = number of more long balloons that round ones
108-144=-36
He has -36 more long balloons that round ones
Or 36 more round balloons that long ones
