1. health-care workers who use latex gloves with glove powder on a daily basis are particularly susceptible to developing a latex allergy. in a sample of 46 hospital employees who had a latex allergy,
he mean number of gloves used per week were 19.3 with a standard deviation of 11.9.

a. find a point estimate for the population mean number of latex gloves used per week by all
health-care workers with a latex allergy.

b. find a 95% confidence interval for the mean number of latex gloves used per week by all
health-care workers with a latex allergy. then, interpret your interval.

answer: -1

step-by-step explanation:

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
