In a random sample of 62 professional actors, it was found that 40 were extroverts. Please find the point estimate, 95% confiden
den301095 [7]

The point Estimate is 0.645 , the confidence interval is (0.525 ,0.764).

<h3>What is Point Estimate ?</h3>

The point estimate is the proportion of success in the sample.

From the data given

p = 40/62

p = 0.645

The point Estimate is 0.645

(b) Confidence interval for true proportion is

\rm {p -Z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}  , p +Z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}

For 95 % Z = 1.96

p =0.645

1-p = 0.355

putting the values

\rm {0.645 -1.96 \sqrt{\dfrac{0.645\times0.355}{62}}  , {0.645 +1.96 \sqrt{\dfrac{0.645\times0.355}{62}} \\

(0.525 , 0.764)

Lower Limit = 0.525

Upper Limit = 0.764

Let A = {15, 25, 35, 45, 55, 65} and B = {25, 45, 65}. What is A ∩ B?
NemiM [27]

Answer:

A∩B={25, 45, 65}

B is a proper subset of A:

B⊂A

Step-by-step explanation:

A∩B means the intersection of the set A and the set B. In other words, is the set of elements contained in these both sets.

Given the set A and the set B:

A ={15, 25, 35, 45, 55, 65}

B ={25, 45, 65}

You can indentify that the numbers common in both sets are: 25,45 and 65.

Therefore you get:

A∩B={25, 45, 65}

Since all elements of B are in A, and A contains elements that are not in B, then B is a proper subset of A:

B⊂A

You are choosing between two plans at a discount warehouse. Plan A offers an annual membership fee of ​$30 and you pay 90​% of t
docker41 [41]

The cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.

<h3>Equation</h3>

Plan A:

  • Membership fee = $30

Manufacturer's recommended list price = 90%

= 90% × 30

= 0.9 × 30

= $27

Total cost of plan A = $30 + $27

= $57

Plan B:

  • Membership fee = $90

Manufacturer's recommended list price = 70%

= 70% × 90

= 0.7 × 90

= $63

Total cost of plan B = $90 + $63

= $153

Therefore, the cost for plan A and plan B at a discount warehouse is $57 and $153 respectively.
