of 50 customers surveyed, 22 of them stated that they would buy a protection
plan.
On the next day, 700 customers came.
Let’s predict how many of them would probably buy the protection plan.
Ratio = 50 : 22 = 700 : x
=> 700 * 22 = 15 400
=> 15 400 / 50 = 308
Thus, if 700 customer came in the next day, around 308 of the customers will
buy life plan.</span>
Answer:
Step-by-step explanation:
Finding the slope (m) of the line the following points in the line, (0, 0) and (2, 20):
y-intercept (b) is 0. The line intercepts the y-axis at 0. Thus, b = 0.
Substitute m = 10 and b = 0 in
The equation in slope-intercept form for the graph would be:
✅
300? Sorry if I’m wrong but that’s what i would’ve put
μ = population mean
σ = 0.05, the population standard deviation
Sample size, n = 6
Sample mean,
= (1.05+1.04+1.01+1.06+0.94+0.99)/6 = 1.015
Because the sample size is less than 30, the confidence interval is
where
t* = 2.015, fromm the t-distribution with dof = 6-1 = 5.
The confidence interval for μ is
1.015 +/- 2.015(0.05/√6) = 1.015 +/- 0.0411 = (0.974, 1.056)
Answer: (0.974, 1.056) liters
