In a study to establish the absolute threshold of hearing, 80 male college freshmen were each seated in a soundproof room and a
Norma-Jean [14]

Answer:

Step-by-step explanation:

Hello!

To study the threshold of hering the researcher took a random sample of 80 male college freshmen.

The students underwent an audiometry test where a tome was played and they had to press a button when they detected it.  The researcher recorded the lowest stimulus level at which the tone was detected obtaining a sample mean of X[bar]= 22.2 dB and a standard deviation of S= 2.1 dB

To estimate the population mean, since we don't have information about the variable distribution but the sample size is greater than 30, you can use the approximation of the standard normal distribution:

X[bar] ± Z_{1-\alpha /2} * \frac{S}{\sqrt{n} }

Where the semiamplitude or margin of error of the interval is:

d= Z_{1-\alpha /2} * \frac{S}{\sqrt{n} }

Using a 95% level Z_{0.975}= 1.965

d= 1.965 * \frac{2.1}{\sqrt{80} }

d= 0.46

The point estimate of the population mean of the threshold of hearing for male college freshmen is X[bar]= 22.2 db

And the estimation using a 95%CI is [21.74;22.66]

I hope this helps!

Karen already owns 3 hair bands, and additional hair bands are priced at 8 for a dollar. How much money does Karen need to spend
kiruha [24]

Answer:

Karen needs to spend $4.5 to buy new hair bands.

Step-by-step explanation:

Given:

Hair bands Karen have = 3

cost of 8 hair bands = $1

Total Hair bands she require = 39

Hence Number of of new hair bands require = Total Hair bands she require - Hair bands Karen have = 39 -3 = 36

we need to find how much money she need to spend to buy new hair bands.

cost of 8 hair bands = $1

Cost of 36 hair bands = money need to spend on hair bands

By using Unitary method we get;

Money spend on new hair bands = \frac{36}{8} = \$4.5

Hence,Karen needs to spend $4.5 to buy new hair bands.
