Given:
difference in the mean weight gain is 0.60 grams
standard deviation of the difference in sample mean is 0.305
68% confidence interval for the population mean difference is a) 0.305
0.60 <u>+</u> 1 * 0.305
0.60 + 0.305 = 0.905
0.60 - 0.305 = 0.295
95% confidence interval for the population mean difference is c) 0.61
0.60 <u>+</u> 2 * 0.305
0.60 + 0.61 = 1.21
0.60 - 0.61 = -0.01
he had 150.
Step-by-step explanation:
i cant explain
Answer:
a . 34
b. 150
Step-by-step explanation:
in the second case firstly add the number in bracket and multiply both the number given
in 1st case first multiply
then add both the product
Answer:
the first thing you do is 50,000 ×3% x1 and multiple it with the percent sign then it will give you 1,500
Answer:
65°
Step-by-step explanation:
recall that for a triangle, the exterior angle (130 deg in this case) is equal to the sum of its remote interior angles (also see attached)
this means that
130° = y° + y°
or
2y° = 130°
y = 130/2 = 65°
