In a random sample of 20 NBA basketball games the mean number of points scored by the home team was 100.4 with a standard deviat

slava [35]

Answer:

The 95% confidence interval is $98.27 < \mu < 102.53$

This interval means that there 95% confidence that the true mean is within this interval

Yes i would agree with my friend because the lower and the upper limit 95% confidence interval for mean points scored at home is greater than 98 points

Step-by-step explanation:

From the question we are told that

The sample size is n = 20

The sample mean is $\mu = 100.4$

The standard deviation is $\sigma = 4.86$

Given that the confidence level is 95% then the level of significance is mathematically evaluated as

$\alpha = 100 - 95$

$\alpha = 5\%$

$\alpha = 0.05$

Next we obtain the critical value of $\frac{ \alpha }{2}$ from the normal distribution table, the value is

$Z_{\frac{ \alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma}{ \sqrt{n} }$

substituting values

$E = 1.96 * \frac{ 4.86 }{ \sqrt{20 } }$

$E = 2.13$

The 95% confidence interval is mathematically represented as

$\= x - E < \mu < \= x + E$

substituting values

$100.4 - 2.13 < \mu < 100.4 + 2.13$

$98.27 < \mu < 102.53$

Which set of values makes the inequality n > -5 true?

xenn [34]

Answer:

all false

Step-by-step explanation:

n > -5

{-5, -5.5, -6} False cannot = -5 ( all are greater than or equal to -5)

{-5, -4.5, -3) False cannot = -5

{-6,0,5} False cannot = -6
