A digital marketing specialist is interested in studying the percent of customers who use online coupons when making an online purchase. To investigate this further, the digital marketing specialist would like to test the claim that the percent of customers who use online coupons when making an online purchase is different than 75%. They decide to complete a hypothesis test at a 10% significance level. They sample 80 online customers, and determine the sample percent to be 90%. The following is the data from this study: Sample size = 80 online customers
Sample proportion = 0.90
Identify the null and alternative hypothesis for this study by filling in the blanks with the correct symbol (E, F, <, or > to represent the correct hypothesis.)

H0 : p = 0.75

H1 : p ≠ 0.75

Step-by-step explanation:

The population proportion, P0 = 0.75 ;

Claim is that proportion of customers who use online coupons when making purchases is actually different than P0 = 0.75 (this is the calm) and the difference could be either more or less

Hence, the null hypothesis H0 : says P0 is 0.75 ;

H0 : p = 0.75

The alternative hypothesis, negating the null hypothesis argues that the proportion is not 0.75 (the difference could be either to the right or left).

H1 : p ≠ 0.75

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
