Adecco Workplace Insights Survey sampled men and women workers and asked if they expected to get a raise or promotion this year

Mumz [18]

Answer:

Yes

Step-by-step explanation:

Let p1 represent proportion of women and p2 proportion of men. The null and alternative hypothesis will be as follows

Null hypothesis

$H_o$ =p2-p1 ≤0

Alternative hypothesis

$H_a$ =p2-p1>0

Sample proportion of women, p1=74/200=0.37

Sample proportion of men is p2=104/200=0.52

Level of significance is 0.01

Pooled proportion= $\frac {104+74}{200+200}=0.445$

Test statistic

$z=\frac {(0.52-0.37)-0}{0.445(1-0.445)*\sqrt{(1/200+1/200)}}=6.9124$

p-value=P(Z≥z)=P(Z≥6.9124)=P(Z≤-6.9124)=0

Since the value of p is less than 0.01, we reject null hypothesis. There’s sufficient evidence that a greater proportion of men is expecting to get a raise

A Ferris wheel has 20 cars that are equally spaced around the circumference of the wheel. The wheel rotates so that the car at t

ss7ja [257]

Answer:

The Ferris wheel rotates 18° between successive cars being at the bottom.

Explanation:

Angle inside a circle = 360°

No of cars in a Ferris wheel = 20

When the bottom of the ride is replaced by the next car, the angle rotated by Ferris wheel is same as the angle between two consecutive cars towards center of Ferris wheel.

Angle between two consecutive cars of Ferris wheel = 360/20 = 18°

The Ferris wheel rotates 18° between successive cars being at the bottom.
