Artyom0805 [142]

Answer: B

Step-by-step explanation: well by graphing the inequality we know it’s a solid line. There’s shading on the right but if you look closely at (0,0), the shading doesn’t go past or near the origin making it B “Does not include the origin”.

Preliminary estimates suggest that about 58% of students at a state university favor implementing an honor code.
gtnhenbr [62]

Answer: c. 1498

Step-by-step explanation:

Given : Preliminary estimates suggest that about 58% of students at a state university favor implementing an honor code.

i.e. p = 0.58

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

Margin of error = 2.5\5=0.025

The formula to find the sample size is given by :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=(0.58)(1-0.58)(\dfrac{(1.96)}{0.025})^2\\\\=1497.302016\approx1498

Hence, the minimum sample size needed = 1498

If a sample of 99 bowlers were taken from a population of 466 bowlers,x could refer to the mean of how many bowlers scores
otez555 [7]

Answer:

99

x is a mean of 99 bowlers scores

Step-by-step explanation:

Sample mean x is the mean of data samples taken from a population.

x is the sample mean

Number of population = 466

Number of samples = 99

Since, x is the mean of data samples, then x is the mean of the 99 sample data taken.

Therefore, x is a mean of 99 bowlers scores.
