From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844

Answer:
y = -1/2x -3
Step-by-step explanation:
The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:
y = mx + b
where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...
y = -1/2x -3
