suter [353]

Answer:

Concept: Modeling expressions

  1. We are given the equation
  2. 200 - 16 {t}^{2}
  3. We want to find the time after 0.75 seconds given that t is represented in seconds.
  4. Hence we do
  5. 200 - 16(0.75)^{2}
  6. Hence we get the answer to 191 feet

How do I solve this STATS question?
k0ka [10]
We have the following data:

Margin of Error = E = 2.7 % = 0.027
Sample size = n = 900
Proportion of adults in favor = p = 60% = 0.6

We need to find the confidence level. For this first we need to find the z value.

The margin of error for a population proportion is given as:

E=z* \sqrt{ \frac{p(1-p)}{n} }

Using the values, we get:

0.027=z* \sqrt{ \frac{0.6*0.4}{900} } \\  \\ 
0.027=z*0.016 \\  \\ 
z= \frac{0.027}{0.01633}  \\  \\ 
z=1.65

As, seen from the z table, z=1.65 corresponds to the confidence level 90%. So, the answer to this question is option B
