Garry decided to bike from his house to his new friend Jerry's house at a rate of 15 miles per hour. Jerry's house is only 10 miles away, but Garry got distracted and rode for 2 hours, passing by Jerry's house by accident. If Garry rode on a number line with each interval equal to 1mile (his house at 0), passing Jerry's house (his house at 10), and stopped after 2 hours after his realization, how many miles away is Garry from Jerry's house?

Step-by-step explanation: Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move.

Answer:
So the value of the test statistic is -0.85.
Step-by-step explanation:
We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.
We get that:
We calculate the standar deviation:
We calculate the value of the test statistic:
So the value of the test statistic is -0.85.
