The height (in inches) of adult men in the United States is believed to be Normally distributed with mean μ . The average height
Jlenok [28]

Answer: a. 69.72 ± 1.37

Step-by-step explanation:

We want to determine a 90% confidence interval for the mean height (in inches) of adult men in the United States.

Number of sample, n = 25

Mean, u = 69.72 inches

Standard deviation, s = 4.15

For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean ± z × standard deviation/√n

It becomes

69.72 ± 1.645 × 4.15/√25

= 69.72 ± 1.645 × 0.83

= 69.72 ± 1.37

The lower end of the confidence interval is 69.72 - 1.37 = 68.35

The upper end of the confidence interval is 69.72 + 1.37 = 71.09

Given the parent function
yanalaym [24]

Answer:

Option a is right.

Step-by-step explanation:

Parent funciton is

f(x) = x^3

The new graph is

f(x) = -2x^3

Since there is no change for x, there is no horizontal shift.

BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.

Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2

Option a is right

i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.

kari74 [83]

Answer: 50%

Step-by-step explanation:

In 2010, there were only 2 bike manufacturers and they had market shares of 30% and 70%.

A new manufacturer joins the market and captures 10% of the market share and Splendor increases to 40% of market share.

Market shares:

Yamaha = 10%

Splendor = 40%

Passion = 100% - 10% - 40%

= 50%
