Answer:
Null Hypothesis, : 60 tissues
Alternate Hypothesis, : < 60 tissues
Step-by-step explanation:
We are given that 60 tissues is the mean number of tissues used during a cold.
Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: sample mean = 52, sample std deviation = 22.
<u><em>Let </em></u><u><em> = mean number of tissues used during a cold.</em></u>
So, Null Hypothesis, : 60 tissues
Alternate Hypothesis, : < 60 tissues
Here, <u><em>null hypothesis states that</em></u> the mean number of tissues used during a cold is more than or equal to 60.
On the other hand, <u><em>alternate hypothesis states</em></u> that the mean number of tissues used during a cold is less than 60.
The test statistics that would be used here is <u>One-sample t test statistics</u> as we don't know about population standard deviation i.e;
T.S. = ~
Hence, the above hypothesis is appropriate for the given situation.
