Answer:

Q1 a) 0.9545

b) 0.02275

c) 0.97725

Q2 z is approximately equal to -1.466

Step-by-step explanation:

Q1 The given information are;

The mean time to commute to work = 24.4 minutes

The standard deviation = 6.5 minutes

a) The z-score for 11.4 is given as follows;

$Z=\dfrac{x-\mu }{\sigma }$

Where;

x = Observed value 11.4

μ = The mean = 24.4 minutes

σ = The standard deviation = 6.5 minutes

$Z=\dfrac{11.4-24.4 }{6.5 } = -2$

The z-score for 37.4 is given as follows;

$Z=\dfrac{37.4-24.4 }{6.5 } = 2$

-2 < z < 2, which gives, from the z-score table;

The probability of commute time to be between 11.4 minutes and 37.4 minutes = 0.97725 - 0.02275 = 0.9545

b) From the z-score table, the probability that the commute time to be less than 11.4 minutes = The probability at z = -2 = 0.02275

c) From the z-score table, the probability that the commute time to be greater than 37.4 minutes = The probability at z = 2 = 0.97725

Q2 The the z-score that corresponds to a commute time of 15 minutes is given as follows;

$Z=\dfrac{x-\mu }{\sigma }$

$Z=\dfrac{15-24.4 }{6.5 } = -\dfrac{94}{65} \approx -1.466$

Mercury, Venus, and Earth are the three planets closest to the Sun. Would their combined distance from the Sun be greater or les

Ganezh [65]

The distance from Mercury to Sun is 57,9 * 10⁶km.
The distance from Venus to Sun is 108,2 *10⁶km.
The distance from Earth to Sun is 149,6 *10⁶km.

57,9 *10⁶+ 108,2 *10⁶+ 149,6 *10⁶ ≈ 315,7 *10⁶km

The distance from Neptune to Sun is 4503 *10⁶km.

That means their combined distanceis less than

methods that seek to alter the social landscape in a very specific way for a given sample of individuals and then track what res

rosijanka [135]

The answer is Quantitative methods.

Quantitative methods that aim to modify the social environment in a very particular way for a specified sample of people and then follow the outcomes of that change; they frequently entail comparisons to a control group that did not receive such an intervention.

What is Quantitative methods ?

Quantitative methods stress objective measurements and statistical, mathematical, or numerical analysis of data gathered through polls, questionnaires, and surveys, as well as through modifying pre-existing statistical data using computing tools.
Online surveys, paper surveys, mobile surveys and kiosk surveys, face-to-face interviews, telephone interviews, longitudinal studies, website interceptors, online polls, and systematic observations are all examples of quantitative data gathering approaches.
For quantitative methods, there are two basic sampling methods: probability sampling and non-probability sampling.
