zvonat [6]
Let present ages of father be x and of son is y years

x/y  = 7/2, 2x=7y, y=2x/7
(y+5)=37/100*(x+5)
(2x/7+5)=37/100*(x+5)
(2x+35)/7=(37x+185)/100
200x+3500=259x+1295
259x-250x=3500-1295
59x=2205
x=37.37 years

zavuch27 [327]

Answer:

t=-2.86

Step-by-step explanation:

From the question we are told that:

Sample 1 n_1=8

Sample 1 mean blood pressure \=x_1=89mmHg

Sample 1 variance \sigma_1=81

Sample 2 n_2=8

Sample 2 mean blood pressure \=x_2=105mmHg

Sample 2 variance \sigma_2=169

Generally the equation for the test of statistic is mathematically given by

t=\frac{\=x_1-\=x_2}{\sqrt{\frac{\sigma_2}{n_1}+\frac{\sigma_2}{n_2} } }

t=\frac{89-105}{\sqrt{\frac{81}{8}+\frac{169}{8} } }

t=-2.86

therefore the samples test for comparing the two population means

t=-2.86
