H(x)

x-5+dx=+5;5x-5(x)+5/h(x)-5x(5)+5

  + h = + 90 = 90° ay + k = 2(1) + 8 = 10+5(x)

In a study of the effect of cigarette smoking on the carbon monoxide diffusing capacity (DL) of the lung, researchers found that
AysviL [449]

Answer:

we conclude that mean DL reading for current smokers is significantly lower than 100 DL

μ ≤ 98.32

Step-by-step explanation:

Given :

H0 : μ = 100

H1 : μ < 100

Given the sample data:

103.768 88.602 73.003 123.086 91.052

92.295 61.675 90.677 84.023 76.014

100.615 88.017 71.210 82.115 89.222

102.754 108.579 73.154 106.755 90.479

Sample mean, xbar = 89.855

Sample standard deviation, s = 14.904

Test statistic :

(Xbar - μ) ÷ (s/√n)

(89.855 - 100) /(14.904/√20)

-10.145 / 3.3326357

Test statistic = - 3.044

Pvalue : using the Pvalue from T score calculator :

Pvalue = 0.00333

Pvalue < α ; Reject H0

Hence, we conclude that mean DL reading for current smokers is significantly lower than 100 DL.

b. Find a 99% upper one-sided confidence bound for the mean DL reading for current smokers. Does this bound confirm your conclusions in part a?

Tcritical at 99% (one sided) = 2.54

Upper confidence interval :

Xbar ± standard Error

Standard Error = Tcritical * s/√n

Standard Error = 2.54 * 14.904/√20 = 8.465

Upper boundary:

Xbar + standard error

89.855 + 8.465 = 98.32

μ ≤ 98.32
