A publisher reports that 38%38% of their readers own a laptop. A marketing executive wants to test the claim that the percentage
Kruka [31]

Answer: - 0.71

Step-by-step explanation:

Let p = population proportion

po = sample proportion.

From the question,

p = 38% = 38/100 = 0.38

po = 32% = 32/100 = 0.32

Sample size (n) = 340.

Since our sample size is greater than 30 ( n= 340) we will be making use of a z test for our test statistics.

The population standard deviation of the data set is given below as

σ = √p(1 - p).

σ = √0.38 (1 - 0.38)

σ = √0.38 × 0.62

σ =√0.2356

σ = 0.49.

Z score = po - p/ (σ/√n)

Z score = 0.32 - 0.38/ (0.49/√340)

Z score = - 0.06 / 0.0266

Z score = - 0.71

If p, q are zeroes of polynomial f(x) =2x^2-7x+3,find the value of p^2+q^2​
Elza [17]

Answer:

p^2 + q^2 = 22/9.

Step-by-step explanation:

For a quadratic function ax^2 + bx + c if the zeroes are A and B then

A + B = -b/a and AB =  c/a.

2x^2 - 7x + 3

Now p and q are the zeroes of the above function so

p + q =  7/3 and pq = 3/2.

Now p^2 + q^2 = (p + q)^2 - 2pq

= (7/3)^2 - 2* 3/2

=  49/9 - 3

= 49/4 -  27/9

= 22/9.
