For each of the situations in parts a) through d), define the parameter (proportion or mean) and write the null and alternative hypotheses in terms of parameter values. Example: We want to know if the proportion of up days in the stock market is 50%. Let pequals=the proportion of up days. Upper H 0 : p equals 0.5H0: p=0.5 vs. Upper H Subscript Upper A Baseline : p not equals 0.5HA: p≠0.5.

We can say that ,Proportion  P of win is

Step-by-step explanation:

Step 1

We first need to check the delivery rate of a machine is 1 in 100

Let denote the proportion of  delivery rate

The null and alternate hypothesis is

Step 2

We need to check whether the mean is changed this year

Let  μ represent the average amount spent

μ=35.32

The null and alternate hypothesis is

μ =35.32

 μ

Step 3

Given that the cure rate is 30% we need to check whether the new drug has the same rate then

Let denote sample proportion of cure rate for the new drug

The null and alternate hypothesis is

Step 4

In this step we need to check whether the website has changed or not so
