Answer:

90 Confidence Interval for the proportion = [ 0.216,0.334]

Step-by-step explanation:

The confidence interval for proportion formula =

p ± z × √p(1 - p)/n

Where p = x/n

x = 42

n = number of samples = 153

p = 42/153

p = 0.2745098039 ≈ 0.275

z = z score of 90% confidence interval = 1.645

Confidence interval =

0.275 ± 1.645 × √0.275 - ( 1 - 0.275)/153

= 0.275 ± 1.645 × √0.0013031046

= 0.275 ± 0.0593820985

Confidence Interval

= 0.275 - 0.0593820985

= 0.2156179015

≈ 0.216

= 0.275 + 0.0593820985

= 0.3343820985

≈ 0.334

90 Confidence Interval for the proportion = [ 0.216,0.334]

mars1129 [50]

Answer:

30 = 80 %

40= 20 %

Step-by-step explanation

I'm sorry for not writing how to do it but it's something like if 30 = 100 then if we had 40 occupying 20 percent of that acid then we will get 32 percent

Which input in this table is incorrect?Cost ofTax onItem Item1.00.082.00 .163.00 .246.00 .5610.00.80Noter all entries are in dol
Norma-Jean [14]

From the table, we can observe that the formula for the total cost of item is

\text{Total cost of item = Cost of item + Tax on item}

From the data in the table, cost of item 6.00 has the input incorrect because the sum of the cost of its item and tax on the item is,

\text{Total cost of item=6.00+56=6.56}

but the total cost was incorrectly inputed as 7.56.

Hence, the correct option is Option A.

There are eight shirts in your closet, three blue, two are black, one is green, and two are white. You randomly select one to we
Maru [420]

The probability of wearing blue shirts on both days is 3/28.

<h3>What is probability?</h3>

Probability is the measure of the likelihood of an occurrence.

Given:

8 shirts are available out of which 3 are blue, 1 is green and 2 are white.

P(blue on Monday) = 3/8

Now, 7 shirts are left to wear on Tuesday

P(blue on Tuesday) =2/7

So,

the probability of wearing blue shirts on both days = 3/8 * 2/7 = 3/28
