A random sample of 450 vacationers in a huge luxury resort showed that 150 were business executives. We want to create a 95% confidence interval for the proportions of vacationers who are business executives.

a) What is the value at the centre of the 95% confidence interval? Write the symbol and value.

Answers

Answer:

p(s) = 0,33

Step-by-step explanation:

n = 450

p₀ = 150/450       p₀ = 0,33      then    q₀  = 0,67

n*p₀ = 0,33*450  =  150

n*q₀  = 0,67*450 = 301

n*p₀  and n*q₀   more than 10, we can approximate  the binomial to a Normal Distribution Distribution

a) p - p₀  = z(c) * √ (p₀q₀)/n

z(c) =  ??

CI   95 %    then α = 5 %    α = 0,05      α/2 = 0,025

z(c) = 1,96

p  =  p₀  ±  z(c) * √ (p₀q₀)/n

p  = 0,33 ± 1,96 * 0,022

p =  (  0,33 - 0,04 ;  0,33 +  0,04

p = ( 0,29  ; 0,37 )

The value of the center of the confidence Interval is 0,33

p(s) = 0,33

4. x = 17

2. x = 77; y = 103

Step-by-step explanation:

4. The acute angles of a right triangle are complementary.

2x + 3x + 5 = 90

5x = 85

x = 17

2.

Same side interior angles are supplementary.

x + 103 = 180

x = 77

y and 103-deg angle are vertical angles, so they are congruent.

y = 103

if if 30 per increase in the salary of usman results in rs.4500 what was the actual salary of usman​

Answers

Answer:

The actual salary of usman was Rs. 3461.53

Step-by-step explanation:

Given that:

Percent increase in salary = 30%

Total salary percent would be = (100+30)% = 130%

Salary after increment = Rs. 4500

Let,

x be the actual salary before increase.

According to given statement,

130% of x = 4500

[tex]\frac{130}{100}x=4500\\1.3x=4500[/tex]

Dividing both sides by 1.3

[tex]\frac{1.3x}{1.3}=\frac{4500}{1.3}\\x=Rs 3461.53[/tex]

Hence,

The actual salary of usman was Rs. 3461.53
