13. Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (u, P, o) for the indicated

parameter.

A psychologist claims that more than 4.1% of the population suffers from professional problems due to extreme shyness. Use P, the true percentage

of the population that suffers from extreme shyness.

OHo:p> 4.1%

Hips 4.1%

OHo: P = 4.1%

H:p> 4.1%

OHo: p < 4.1%

Hip 24.1%

OHo: P = 4.1%

Hip < 4.1%

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b.the means of the data sets are within 3 units from eachother. c.the data sets have the same standard deviation. d.the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°
