Construct a 95% confidence interval for the population mean, μ. Assume the population has a normal distribution. A random sample

GuDViN [60]

Answer: $(628.48,\ 661.52)$

Step-by-step explanation:

Given : Sample size : $n=16$ , which is a small sample (, 30) so we use t-test.

Sample mean : $\overline{x}=645 \text{ hours}$

Standard deviation : $\sigma = 31 \text{ hours}$

Significance level : $\alpha=1-0.95=0.05$

Critical value : $t_{n-1,\alpha/2}=2.131$

The confidence interval for population mean is given by :-

$\overline{x}\pm t_{n-1,\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=645\pm(2.131)\dfrac{31}{\sqrt{16}}\\\\\approx645\pm16.52\\\\=(645-16.52,\ 645+16.52)\\\\=(628.48,\ 661.52)$

Hence, a 95% confidence interval for the population mean $\mu$ = $(628.48,\ 661.52)$

Help anyone need it asap 8th grade math

Oliga [24]

Answer:

x = 1

Step-by-step explanation:

2x + 8 = 4x + 6

subtract 6 from both sides of the equation

2x + 8 - 6 = 4x + 6 - 6

2x + 2 = 4x

subtract 2x from both sides of the equation

2x - 2x + 2 = 4x - 2x

2 = 4x - 2x

2 = 2x

divide both sides of the equation by 2

2/2 = 2x/2

1 = x
