0.9192433

Step-by-step explanation:

Given : A nationwide study of American homeowners revealed that 65% have one or more lawn mowers.

i.e. Population proportion :

A  lawn equipment manufacturer, located in Omaha, feels the estimate is too low for households in Omaha.

Then, his hypothesis will be :-

Since, the alternative hypothesis is left tailed , so the test is a left-tailed test.

Sample size : n= 497

The sample proportion of people ad one or more lawn mowers=

Test statistic for proportion :-

i.e.

Now, by using the standard normal table for z , we have

P-value (left tailed) =

good luck!

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
