Answer:

Step-by-step explanation:

The population average number of raisins per box is 30.

The type of statistical analysis to be run here is the inferential statistical analysis and its assumptions include normality, linearity and equality of variance.

Null hypothesis: Average number of raisins per box is 30: u = 30

Alternative hypothesis: Average number of raisins per box is not 30: u ≠ 30

To perform a two tailed single sample test, we have

z statistic = (the sample mean - hypothesized mean) / (SD/√n)

sample mean = 28.05, SD = 3.87 hypothesized mean = 30 n = 36

Thus, we have 28.05 - 30 / (3.87/√36)

= -1.95 / (3.87/6)

= -1.95 / 0.645

= -3.023

we say this is a left tailed test and use the negative z table

where -3.02 = 0.0013

To determine whether the average number of raisins per box differs from the expected 30.

Using p < 0.05, since the observed value 0.0013 is less than 0.05, we conclude the the average number of raisins per box differs from the expected 30.

Both radio stations will play the same song on the same day 5 times in 30 days.

Explanation

A radio station plays yesterday by the Beatles once every 2 days. Another station plays the same song once every 3 days.

For finding the day on which both radio stations will play the same song, we will just find the LCM(Least Common Multiplier) of 2 and 3. So, the LCM will be 6.

That means, on every 6th day, both radio stations will play the same song.

So, the number of times that both radio stations will play the same song on the same day in 30 days $=(\frac{30}{6})= 5$
