sleet_krkn [62]

Question

<em>In a study of 100 new cars, 29 are white. Find p and q , where p is the proportion of new cars that are white. </em>

Answer:

p = 0.29 and q = 0.71

Step-by-step explanation:

Given

Total new cars = 100

White new cars = 29

Required

Determine p and q

From the question;

<em>p represents white new cars</em>

Hence;

$p = 29$

Note that;

$p + q = 100$

Substitute 29 for p

$29 + q = 100$

$29 - 29 + q = 100 - 29$

$q = 100 - 29$

$q = 71$

The proportion of p is calculate by dividing p by the total number of new cars (Same process is done for q)

For proportion of p

$Proportion,\ p = \frac{p}{new\ cars}$

$Proportion,\ p = \frac{29}{100}$

$Proportion,\ p = 0.29$

For proportion of q

$Proportion,\ q = \frac{q}{new\ cars}$

$Proportion,\ q = \frac{71}{100}$

$Proportion,\ q = 0.71$

A normal distribution has a mean of 85.3 and a standard deviation of 4.85. Find the data value corresponding to the value of z g

Mazyrski [523]

Answer: 87.9675

Step-by-step explanation:

Formula for z:

$z=\dfrac{x-\mu}{\sigma}$ , where x= data value corresponding to z, $\mu$ = mean, $\sigma$ = standrad deviation.

Given: $\mu$ =85.3, $\sigma$ =4.85, z=0.55

To find : x

$0.55=\dfrac{x-85.3}{4.85}\\\\\Rightarrow\ 0.55\times4.85=x-85.3\\\\\Rightarrow\ 2.6675=x-85.3\\\\\Rightarrow\ x=85.3+2.6675\\\\\Rightarrow\ x=87.9675$

Hence, The required data value= 87.9675
